After a woman was raped, she finds herself pregnant and wants to know whether the father is her husband or the suspected rapist. The paper DNA is cut, run on a gel, and probed, all in simulation. Students can see how restriction enzymes, gel electrophoresis, and probe hybridization work. Students learn the basic results of restriction enzymes, gel electrophoresis, and probe hybridization. Students will explain how a DNA profile may be used in forensic identification.
Students explain how alleles are inherited in Mendelian fashion.
Students first assemble DNA strips representing a standard, the mother, the husband, the suspect, and the baby. The remaining sequences represent an autoradiograph, and paternity can be deduced.
