OPINION
ANDERSON, RUSSELL A., Justice.
Tony Allen Roman Nose, appellant, appeals from his conviction of first-degree murder during the commission of criminal sexual conduct in violation of Minn.Stat. § 609.185(2) (2000) for the July 11, 2000, killing of Jolene Stuedemann. Appellant claims that the trial court erred by failing to conduct a pretrial Frye-Mack hearing on the general acceptance within the relevant scientific community of the PCR-STR method of testing deoxyribonucleic acid (DNA) used by the Minnesota Bureau of Criminal Apprehension (BCA) in this case. Appellant also claims that the trial court erred by admitting the DNA evidence in this case, arguing that the state failed to show reliability under the second prong of the Frye-Mack standard, and by admitting certain other evidence. Appellant also claims prosecutorial misconduct. We conclude that the trial court erred when it failed to conduct a Frye-Mack hearing on the general acceptance within the relevant scientific community of the method of testing DNA used here and remand for hearing to determine if the PCR-STR method of testing DNA has obtained general acceptance within the relevant scientific community. We retain jurisdiction in order to resolve the other issues raised by appellant after that hearing, if necessary.
On July 11, 2000, the body of 17-year-old Jolene Stuedemann, an apparent homicide victim, was found by her sister in their home in Woodbury, Minnesota. A medical examiner determined, based on an examination of the body at the scene and an autopsy, that Stuedemann had been beaten and stabbed multiple times with a screwdriver, had been sexually assaulted, and that she bled to death as a result of multiple stab wounds inflicted during the sexual assault. An investigation led authorities to appellant.
Appellant, who was 17 years old when Stuedemann was killed, was a resident of a group home in Woodbury during the school year. Appellant normally returned to Montana during the summer months. Appellant testified that on the night before Stuedemann's body was discovered he decided to break group home rules so that he would be returned to Montana. On the evening prior to Stuedemann's homicide, appellant went to the home of his friend, Andy Reiman, who was dating Stuede-mann and who lived about a mile from the group home. Reiman and Stuedemann re turned to Reiman's home, where they encountered appellant in the driveway, listening to his walkman. All three went into Reiman's home where they drank beer and watched television. Appellant claimed that Stuedemann also gave him some marijuana and that Stuedemann and he did some "coke."
Appellant testified that he was sitting on the couch listening to music with his eyes shut, and that when he opened his eyes, Reiman and Stuedemann were engaged in sexual intercourse. According to appellant, he and Stuedemann than had sex while Reiman slept. Reiman testified, however, that he did not fall asleep immediately after he and Stuedemann had sex and that he was certain that Stuedemann did not have sex with appellant.
Appellant fell asleep. Stuedemann left at 3:30 a.m. while appellant was sleeping. Reiman woke appellant and told him to leave as well. Appellant left at approximately 4 a.m. and eventually returned to the group home.
Because appellant had been reported as a runaway the night before, the house parent notified police of appellant's return to the group home, and a Woodbury police officer interviewed appellant. Appellant told the officer that he had been with Reiman the night before. The officer then left the group home and responded to a call that resulted in discovery of Stuede-mann's body. Investigators discovered part of a set of headphones under Stuede-mann's body. A piece of crumpled paper was found in Stuedemann's mouth with a fingerprint on it, later identified as appellant's, and a blood-stained screwdriver was found near her body.
Eventually, the house parent learned of blood-stained clothing that had been placed in a trash bag in the garage of the group home and that belonged to appellant, and she notified authorities. The lower half of a set of headphones was found in the group home's kitchen garbage. A forensic scientist determined that the headphones found in the garbage and the part of a set of headphones found under Stuedemann's body could have been a match. Authorities also found bloodstained underwear and a walkman with no headphones attached in appellant's bedroom.
Appellant testified at trial and offered a version of events different from the state's theory of the case. According to appellant, after he left Reiman's home he began walking toward the group home and realized that he no longer had his walkman. He attempted to sneak into the group home, but failing that, he went to Stuede-mann's home, about a half-mile from the group home. There, he found the lights on but nobody answered the door. He was concerned Stuedemann had overdosed so he entered the home through the back door and there he discovered her body. Appellant testified that he ran inside, knelt on one knee beside the body, saw some paper in her mouth and tried to pull it out, but could not, and that he then saw his walkman next to Stuedemann's body. Appellant testified that he did not call police because he was scared, since he had used drugs and had sex with Stuedemann, had her blood on his clothing, and his walkman was next to Stuedemann's body. Appellant testified that he vomited in the toilet, took his walkman, and ran back to the group home. Appellant changed his clothes and slept in a van in front of the group home until later in the morning. He told a house parent that he changed his clothes because he had spilled beer on them.
The state offered DNA evidence at trial that was obtained from DNA testing of samples taken from the crime scene and the group home. The DNA testing was conducted by the BCA using the PCR-STR method. The DNA evidence showed that the DNA profile of blood samples taken from the screwdriver and appellant's personal property found at the group home matched Stuedemann's DNA profile and that semen samples taken from Stue-demann's body matched appellant's DNA profile. Before trial, appellant requested a Frye-Mack hearing to determine first, whether the PCR-STR method of testing DNA is generally accepted within the relevant scientific community and second, whether the state could establish the necessary foundation for admission of the test results in this case. The trial court granted a hearing only on the second issue. Following the limited Frye-Mack hearing, the court ruled the DNA test results admissible.
Appellant was found guilty by a Washington County jury of murder in the first degree while committing or attempting to commit criminal sexual conduct and premeditated murder in the first degree. The court entered conviction only on the charge of murder in the first degree while committing or attempting to commit criminal sexual conduct in the first or second degree under Minn.Stat. § 609.185(2), and sentenced appellant to life in prison without parole. Appellant appeals the decision of the trial court denying a Frye-Mack hearing on the general acceptance of the PCR-STR method of testing DNA, the trial court's ruling on prong two of the Frye-Mack standard, and the trial court's evidentiary rulings. Appellant also argues that the state committed prosecutorial misconduct. Appellant argues that he was denied his right to a fair trial and seeks a new trial.
We must determine whether the trial court erred when it denied appellant's request for a pretrial Frye-Mack hearing to determine whether the PCR-STR method of testing DNA has gained general acceptance within the relevant scientific community. We begin our analysis with a brief overview of the Frye-Mack standard for determining admissibility of scientific evidence and its development in Minnesota.
In our decision in State v. Kolander, 236 Minn. 209, 221-22, 52 N.W.2d 458, 465 (1952), we adopted the standard for the admissibility of evidence obtained from new scientific techniques that was set forth in Frye v. United States, 293 F. 1013, 1014 (D.C.Cir.1923), which requires "general acceptance in the particular field in which [the scientific principle or discovery] belongs." Frye, 293 F. at 1014. Subsequently, we stated in our decision in State v. Mack, 292 N.W.2d 764, 768 (Minn.1980), that "the results of mechanical or scientific testing are not admissible unless the testing has developed or improved to the point where experts in the field widely share the view that the results are scientifically reliable as accurate." We stated that the particular evidence must have a foundation that is scientifically reliable. As a result of Frye and Mack, a two-pronged standard has emerged in Minnesota that must be satisfied before scientific evidence may be admitted. First, a novel scientific technique that produces evidence to be admitted at trial must be shown to be generally accepted within the relevant scientific community, and second, the particular evidence derived from the technique and used in an individual case must have a foundation that is scientifically reliable. Goeb v. Tharaldson, 615 N.W.2d 800, 810 (Minn. 2000) (reaffirming adherence to Frye-Mack standard after Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 118 S.Ct. 2786, 125 L.Ed.2d 469 (1993)). Put another way, the Frye-Mack standard asks first whether experts in the field widely share the view that the results of scientific testing are scientifically reliable, and second whether the laboratory conducting the tests in the individual case complied with appropriate standards and controls. State v. Jobe, 486 N.W.2d 407, 419 (Minn.1992).
The trial court determines whether the Frye-Mack standard has been satisfied by means of a pretrial hearing. When the scientific technique that produces the scientific evidence is no longer novel or emerging, then the pretrial hearing should focus on the second prong of the Frye-Mack standard. See Jobe, 486 N.W.2d at 420.
In this case the trial court denied appellant's request for a hearing on general acceptance of the PCR-STR method within the relevant scientific community. We must determine, then, whether evidence obtained from the PCR-STR method of testing DNA is novel, such that a pretrial hearing should have been conducted to determine whether the PCR-STR method has gained general acceptance within the relevant scientific community.
We have considered the general acceptance within the scientific community of DNA testing and the admissibility of DNA evidence in earlier decisions. See, e.g., State v. Johnson, 498 N.W.2d 10, 14 (Minn.1993); Jobe, 486 N.W.2d at 419-20; State v. Schwartz, 447 N.W.2d 422, 427-28 (Minn.1989); see also State v. Bloom, 516 N.W.2d 159, 160-69 (Minn.1994); State v. Nielsen, 467 N.W.2d 615, 619-20 (Minn.1991). DNA typing is generally acceptable, Schwartz, 447 N.W.2d at 426, and we do not question the theory of human genetics underlying DNA testing and the basic validity of DNA analysis. Bloom, 516 N.W.2d at 164.
Our previous analysis was of the RFLP method of testing DNA, however. Relying on Schwartz, we stated in Jobe that the required Frye-Mack hearing "should focus only on whether the laboratory which did the testing was in compliance with the appropriate standards and controls. It should not be a forum for challenging the basic DNA RFLP testing procedures themselves." Jobe, 486 N.W.2d at 420 (footnote omitted). We concluded in Jobe that the RFLP method should no longer be challenged in a pretrial Frye-Mack hearing because the general acceptance of the RFLP method had been established at the trial court level by means of a Frye-Mack hearing and affirmed by this court in Schwartz, 447 N.W.2d at 425. See Jobe, 486 N.W.2d at 420.
The state points to the decisions of other appellate courts that have upheld admission of DNA evidence obtained from PCR-STR testing to argue that a Frye-Mack hearing on general acceptance of the PCR-STR method is unnecessary. See People v. Allen, 72 Cal.App.4th 1093, 85 Cal.Rptr.2d 655, 659-60 (1999); People v. Shreck, 22 P.3d 68, 83 (Colo.2001); Commonwealth v. Rosier, 425 Mass. 807, 685 N.E.2d 739, 743 (1997); State v. Jackson, 255 Neb. 68, 582 N.W.2d 317, 325 (1998); State v. Butterfield, 27 P.3d 1133, 1143 (Utah 2001). However, other jurisdictions have different standards for the admissibility of evidence obtained from scientific techniques, some adhering to the federal Daubert standard and others to state rules of evidence. See, e.g., Shreck, 22 P.3d at 72 (state rule of evidence); Rosier, 685 N.E.2d at 741 (Daubert standard); Butterfield, 27 P.3d at 1142 (state rule of evidence). In addition, even those appellate decisions that affirmed the admissibility of DNA evidence obtained from PCR methods of testing DNA generally did so only after reviewing the findings and conclusions of the trial court following an eviden-tiary hearing. See, e.g., Beasley, 102 F.3d at 1445, 1447-48; Brodine, 936 P.2d at 548, 550-51; Tankersley, 956 P.2d at 491-92; Shreck, 22 P.3d at 72, 80; Rosier, 685 N.E.2d at 741-43; Carter, 586 N.W.2d at 826, 828; Jackson, 582 N.W.2d at 324-25; Butterfield, 27 P.3d at 1137-38, 1145. The decisions of other appellate courts may be relevant evidence at an evidentiary hearing on the general acceptance of a scientific technique within the relevant scientific community. To rely exclusively on decisions of other appellate courts rather than on the testimony of expert witnesses to establish general acceptance, however, would be a departure from our precedent requiring a Frye-Mack hearing to determine general acceptance within the relevant scientific community.
General acceptance within the relevant scientific community of the PCR-STR method of testing DNA is not a matter this court has previously addressed. The PCR-STR method is a new method of testing DNA that has emerged as an evidence-producing scientific technique. The state asserts that because the PCR-STR method has been used by the BCA since February 1999, it is no longer a novel scientific technique and a Frye-Mack hearing is therefore unnecessary to determine its general acceptance within the relevant scientific community. However, we have not decided general acceptance for Minnesota courts. The BCA's practice is not dispositive of the issue, but may instead be relevant evidence at the Frye-Mack hearing to determine whether the technique has in fact gained general acceptance within the relevant scientific community. Once this court has reviewed and confirmed the general acceptance of a scientific technique, then the evidence produced by the technique may be admitted without the need for a pretrial hearing on the first prong of the Frye-Mack standard, as with RFLP DNA. See, e.g., Jobe, 486 N.W.2d at 420.
Because the PCR-STR method is a new scientific technique that this court has never before considered, and because it is sufficiently different from the RFLP method, the evidence obtained from the technique is novel scientific evidence. It therefore requires not only a Frye-Mack hearing on the procedures and controls involved in the individual case but also a hearing on the general acceptance of the technique within the relevant scientific community before evidence obtained from the method is admissible. Goeb, 615 N.W.2d at 814. That the RFLP method of testing DNA has gained general acceptance does not permit evidence obtained from significantly different methods of DNA testing to be admitted without holding a hearing on the first prong of the Frye-Mack standard. See Goeb, 615 N.W.2d at 814. Rather, when novel scientific evidence is offered that has not been reviewed by this court, the district court must determine whether the method of producing the scientific evidence is generally accepted in the relevant scientific community. Id.
Even if it appears likely that in the course of a Frye-Mack hearing on the PCR-STR method of testing DNA the trial court will determine that the method has gained general acceptance within the relevant scientific community, the likelihood of such a determination should not be the basis for denying a Frye-Mack hearing. When a district court conducts a Frye-Mack hearing only for a method of testing DNA that appears to the district court to be controversial or unsettled in the relevant scientific community, there is a risk that the judge is put in the role of scientist, a role that we rejected in Goeb. Goeb, 615 N.W.2d at 812-14. Rather, Goeb makes it clear that the district court is required to conduct a Frye-Mack hearing on the general acceptance of scientific techniques that are novel before evidence may be introduced at trial. 615 N.W.2d at 814. We therefore conclude that the trial court improperly denied appellant his right to a pretrial Frye-Mack hearing on the general acceptance within the relevant scientific community of the PCR-STR method of testing DNA.
Appellant is entitled to a new trial only if the evidence was erroneously admitted and he suffered prejudice, however. See State v. Jones, 556 N.W.2d 903, 910 (Minn.1996). The dissent asserts that even if the trial court improperly denied appellant a Frye-Mack hearing on general acceptance and therefore admitted the DNA evidence in error, the error was harmless beyond a reasonable doubt. We disagree. The relevant standard for determining harmless error is whether the jury's verdict is " 'surely unattributable' " to the error. State v. Juarez, 572 N.W.2d 286, 292 (Minn.1997) (citing Jones, 556 N.W.2d at 910). The DNA evidence in this case was specifically used to discredit appellant's theory of the case, namely, that an unidentified third party sexually assaulted and murdered Stuedemann. The state argued that there was no evidence of any other contributor to the DNA samples and that therefore the person whose DNA profile matched the DNA profile of the semen samples had to be the killer. We simply cannot say that the jury's verdict was surely unattributable to the1 admission of this DNA evidence given the importance that was placed on the evidence.
To determine whether the evidence was admissible, we remand the case to the trial court for a hearing on whether the PCR-STR method of testing DNA has gained general acceptance within the relevant scientific community. The hearing shall be concluded within 90 days of the filing of this opinion and, within 60 days thereafter, the trial court shall file its findings and conclusions with this court. In the .meantime, this appeal is stayed. Appellant shall move the court to lift the stay in accordance with Minn. R. of Civ.App. P. 127 within 30 days after the trial court has filed its findings and conclusions in the district court.
Appeal stayed, jurisdiction retained, and remanded for hearing.
MEYER, J., not having been a member of this court at the time of the argument and submission, took no part in the consideration or decision of this case.
. PCR stands for "polymerase chain reaction" technique. There are various methods of the PCR technique. STR is the newest PCR method and stands for "short tandem repeat" technology. The PCR-STR method of testing DNA has been used by the BCA since February 1999.
. In Daubert, the U.S. Supreme Court recognized that the Frye test was superseded by the adoption of the Federal Rules of Evidence and that the Federal Rules of Evidence do not contain a "general acceptance" requirement for the admissibility of scientific evidence. 509 U.S. at 587-88, 113 S.Ct. 2786.
. When a new scientific technique emerges, such as the PCR-STR method of testing DNA, the evidence obtained from that technique is not admissible unless the technique for obtaining the evidence has been generally accepted within the relevant scientific community. Goeb, 615 N.W.2d at 810. The dissent analyzes the limited record that accompanies appellant's motion for a Frye-Mack hearing on general acceptance and the state's answer to the motion and concludes that the state has met its burden of demonstrating that the PCR-STR method is generally accepted. However, the issue of whether a technique is generally accepted within the relevant scientific community is best determined by eviden-tiary hearing. See Goeb, 615 N.W.2d at 814. There was no evidentiary hearing on general acceptance in this case and, contrary to the dissent's argument, hearings before other district courts will not substitute for the eviden-tiary hearing required here. Without an evi-dentiary hearing on the views of the relevant scientific community, trial and appellate judges become scientists, an approach we clearly rejected in Goeb. 615 N.W.2d at 813-14. Our review of the issue of general acceptance of the PCR-STR method of testing DNA will focus on the trial court's findings and conclusions and the record of the evidentiary hearing we here order.
. The state also cites decisions that upheld admissibility of evidence obtained from other PCR methods. See United States v. Beasley, 102 F.3d 1440, 1447 (8th Cir.1996); Brodine v. State, 936 P.2d 545, 550-51 (Alaska Ct.App.1997); State v. Tankersley, 191 Ariz. 359, 956 P.2d 486, 492 (1998); State v. Carter, 255 Neb. 591, 586 N.W.2d 818, 826 (1998); State v. Harvey, 151 N.J. 117, 699 A.2d 596, 624 (1997).
. The dissent points out that every appellate court that has reviewed DNA evidence obtained from the PCR-STR method has approved its admission and further argues that our holding "sets Minnesota apart from the worldwide scientific community that has accepted this test." However, we do not decide today that the PCR-STR method is not a generally accepted scientific technique. Rather, we conclude that its general acceptance has not been established by evidentiary hearing. Indeed, our disposition is consistent with other appellate courts in that virtually all of the appellate decisions cited affirmed admission of DNA evidence obtained from the PCR-STR method only after an evidentiary hearing. No evidentiary heáring was held here. It is not enough for us to believe the test has gained general acceptance in the relevant scientific community. The state must establish that it has gained general acceptance, and it must do so by evidentiary hearing. Thus, we are adhering to our precedent, which requires a hearing on general acceptance before novel scientific evidence is admissible, and our holding is consistent with the practice of other appellate courts.
. DNA, a long, double-stranded molecule, is found in chromosomes in cell nuclei. It is found in all cells that have a nucleus. Most sections of DNA vary little among individual human beings. Polymorphic sections, however, do vary. If two fragments do not match, then they could not share a common source, but if they do match, then they may have a common, source. The underlying theory of forensic use of DNA profiles is that as the number and variability of the polymorphisms used in the typing procedure increases, the odds of two people having the same profile decreases. Bloom, 516 N.W.2d at 161 (and citations therein).
Testimony at the Frye-Mack hearing in this case provides some explanation of the significant differences between the RFLP and PCR-STR methods of testing DNA. "Restriction fragment length polymorphism" was the first DNA technique used in forensic laboratories and is a lengthy process typically requiring four to six months. Using RFLP, scientists take a known sample of DNA and an unknown sample from the crime scene or from other evidence. The scientists extract DNA from the samples, cut it up into fragments, separate the fragments, locate the loci of the DNA that vary greatly among people, and then look at the DNA at those loci. The result is a type of bar code that can be used to compare the two samples to see how closely they match. The RFLP technique requires a high molecular weight DNA and a large amount of DNA — typically 500 nanograms to one microgram. Scientists are unable to get results using degraded DNA samples. The technique involves the use of radiation and consumes the DNA during testing.
The "polymerase chain reaction" technique, on the other hand, is a process by which DNA fragments too small to be suitable for the RFLP method can be analyzed because the technique requires much smaller quantities of DNA — the BCA uses between .5 and one nanogram of DNA. Furthermore, PCR involves no use of radiation and can be used on degraded samples of DNA. The technique involves extracting a small amount of DNA and then amplifying the DNA many times over using the polymerase chain reaction technique to increase the size of the sample before it can be subjected to analysis. Amplification involves three separate steps, none of which is used in the RFLP method.
. The dissent disputes our conclusion that the PCR-STR method is significantly different from the RFLP method and asserts that there is nothing in the record that indicates a "qualitative difference between one copy and many copies [of DNA] ." The dissent is focusing on the results of the PCR technique rather than on the process of the PCR technique itself. We have already stated that we do not question the science of DNA analysis; however, the scientific method used to obtain a DNA sample that can be subjected to DNA analysis is the science that is at issue here. And the polymerase chain reaction technique, used here to obtain a DNA sample that can be analyzed, is a scientific method that the state's own DNA expert witness testified is different from the RFLP method. See note 6 supra. Because the PCR technique is a new scientific method used to obtain a DNA sample that can be analyzed, the state bears the burden of establishing its general acceptance and its foundational reliability by means of an evidentiary hearing before evidence obtained from the technique may be admitted. That has not occurred in this case.
. The dissent's approach to look to other appellate decisions to conclude that the PCR-STR method has gained general acceptance would eliminate the requirement of a pretrial evidentiary hearing on general acceptance, an important step in our time-tested procedure for admitting scientific evidence, apparently because the hearing may be "time-consuming and costly." This approach ignores the important purpose that the Frye-Mack hearing on general acceptance serves, which is to ensure "that the persons most qualified to assess scientific validity of a technique have the determinative voice." Goeb, 615 N.W.2d at 813.
. The dissent argues that we should take "judicial notice" of the inherent reliability of the PCR-STR method of testing DNA unless something in the record indicates a reason to depart from the findings of other jurisdictions. But that is not the procedure we have established for determining the admissibility of scientific evidence. Moreover, there is an inadequate record to support taking judicial notice of the general acceptance of the PCR-STR method because appellant's request for a hearing on the issue was denied by the trial court.
The dissent argues that there is overwhelming evidence that the PCR-STR method is generally accepted. Even so, the established procedure for determining general acceptance must be followed. Much, if not all, of the evidence relied on by the dissent may be admissible evidence at the required evidentia-ry hearing. The dissent further argues that appellant did not provide any evidence to refute the state's evidence. The proponent of evidence obtained from a scientific test bears the burden of showing its reliability. See Goeb, 615 N.W.2d at 814; State v. Moore, 458 N.W.2d 90, 97-98 (Minn.1990). As we have already made clear, this is done by means of an evidentiary hearing. Appellant did argue in his motion requesting a Frye-Mack hearing that "PCR testing is distinguishable from RFLP testing in that PCR testing involves amplifying (or 'copying') a DNA sample in a laboratory to increase the si2e of the sample." Further opportunity to develop the record and to refute the general acceptance of the PCR-STR method was denied appellant because his motion for a hearing on general acceptance was denied. Nevertheless, ample evidence was offered during the second prong of the Frye-Mack hearing by the state's expert DNA witness that the two techniques are significantly different, which the dissent appears to disregard.
