is_impossible: yes

question: What two categories are pseudogenes classified into?
is_impossible: yes

question: What do you use to calculate genome size?
is_impossible: yes

question: What are gene clusters a large part of?
is_impossible: yes
context: The term was created in 1920 by Hans Winkler, professor of botany at the University of Hamburg, Germany. The Oxford Dictionary suggests the name to be a blend of the words gene and chromosome. However, see omics for a more thorough discussion. A few related -ome words already existed—such as biome, rhizome, forming a vocabulary into which genome fits systematically.

question: How is halving genetic material in linear chains of DNA accomplished?
is_impossible: yes

question: What is one thing the term transposable elements can be applied to mean?

question: What three non-chromosomal genetic elements can bacteria comprise?
is_impossible: yes

question: What organization feature do prokaryotes have?
is_impossible: yes

question: Why was the Genoscope created?
is_impossible: yes

question: What is being done on single cell silico?
is_impossible: yes
context: Some organisms have multiple copies of chromosomes: diploid, triploid, tetraploid and so on. In classical genetics, in a sexually reproducing organism (typically eukarya) the gamete has half the number of chromosomes of the somatic cell and the genome is a full set of chromosomes in a diploid cell. The halving of the genetic material in gametes is accomplished by the segregation of homologous chromosomes during meiosis. In haploid organisms, including cells of bacteria, archaea, and in organelles including mitochondria and chloroplasts, or viruses, that similarly contain genes, the single or set of circular or linear chains of DNA (or RNA for some viruses), likewise constitute the genome. The term genome can be applied specifically to mean what is stored on a complete set of nuclear DNA (i.e., the "nuclear genome") but can also be applied to what is stored within organelles that contain their own DNA, as with the "mitochondrial genome" or the "chloroplast genome". Additionally, the genome can comprise non-chromosomal genetic elements such as viruses, plasmids, and transposable elements.

qas: question: What is the science that deals with the common genetic characteristics of related organisms called?

is_impossible: yes

question: What do genome not use as intermediate?
is_impossible: yes

question: Whose genome map greatly aided the Human Genome Project?
is_impossible: yes
context: When people say that the genome of a sexually reproducing species has been "sequenced", typically they are referring to a determination of the sequences of one set of autosomes and one of each type of sex chromosome, which together represent both of the possible sexes. Even in species that exist in only one sex, what is described as a "genome sequence" may be a composite read from the chromosomes of various individuals. Colloquially, the phrase "genetic makeup" is sometimes used to signify the genome of a particular individual or organism.[citation needed] The study of the global properties of genomes of related organisms is usually referred to as genomics, which distinguishes it from genetics which generally studies the properties of single genes or groups of genes.

qas: question: What is the relation between the number of base pairs and total complement of genes in a species called?

is_impossible: yes

question: How far can genetic novelty go?
is_impossible: yes

question: What is known as the study of the properties of single or groups of sex chromosomes?
is_impossible: yes
context: Both the number of base pairs and the number of genes vary widely from one species to another, and there is only a rough correlation between the two (an observation known as the C-value paradox). At present, the highest known number of genes is around 60,000, for the protozoan causing trichomoniasis (see List of sequenced eukaryotic genomes), almost three times as many as in the human genome.

is_impossible: yes

question: What are people referring to when they say species exist in one sex?
is_impossible: yes

question: What do genome not use as intermediate?
is_impossible: yes
context: In 1976, Walter Fiers at the University of Ghent (Belgium) was the first to establish the complete nucleotide sequence of a viral RNA-genome (Bacteriophage MS2). The next year Fred Sanger completed the first DNA-genome sequence: Phage Φ-X174, of 5386 base pairs. The first complete genome sequences among all three domains of life were released within a short period during the mid-1990s: The first bacterial genome to be sequenced was that of Haemophilus influenzae, completed by a team at The Institute for Genomic Research in 1995. A few months later, the first eukaryotic genome was completed, with sequences of the 16 chromosomes of budding yeast Saccharomyces cerevisiae published as the result of a European-led effort begun in the mid-1980s. The first genome sequence for an archaeon, Methanococcus jannaschii, was completed in 1996, again by The Institute for Genomic Research.

is_impossible: yes

question: A gamate has how many chromosomes relative to a somatic cell?
is_impossible: yes

question: What is a term that can describe how DNA transposons move?
is_impossible: yes
context: The development of new technologies has made it dramatically easier and cheaper to do sequencing, and the number of complete genome sequences is growing rapidly. The US National Institutes of Health maintains one of several comprehensive databases of genomic information. Among the thousands of completed genome sequencing projects include those for rice, a mouse, the plant Arabidopsis thaliana, the puffer fish, and the bacteria E. coli. In December 2013, scientists first sequenced the entire genome of a Neanderthal, an extinct species of humans. The genome was extracted from the toe bone of a 130,000-year-old Neanderthal found in a Siberian cave.

is_impossible: yes

question: What do most viruses more complex than plasmids carry?
is_impossible: yes
context: New sequencing technologies, such as massive parallel sequencing have also opened up the prospect of personal genome sequencing as a diagnostic tool, as pioneered by Manteia Predictive Medicine. A major step toward that goal was the completion in 2007 of the full genome of James D. Watson, one of the co-discoverers of the structure of DNA.

qas: question: What is the term for something that lists the important and notable parts of a genome?

is_impossible: yes

question: What does horizontal gene transfer explain about nuclear chromosomes?
is_impossible: yes

question: Which company has led the way in sequencing of individual genetic makeup?
is_impossible: yes
context: Whereas a genome sequence lists the order of every DNA base in a genome, a genome map identifies the landmarks. A genome map is less detailed than a genome sequence and aids in navigating around the genome. The Human Genome Project was organized to map and to sequence the human genome. A fundamental step in the project was the release of a detailed genomic map by Jean Weissenbach and his team at the Genoscope in Paris.

qas: question: What is the term that accounts for the constituents of the haploid genome?

answers: text: evolutionary history
is_impossible: no

question: What is the history of a genome used for?
is_impossible: yes

question: What should be included in the history of a genome?
is_impossible: yes

is_impossible: yes

question: What does having more protein coding genes not mean?
is_impossible: yes

question: What does cut and paste help metazoan do?
is_impossible: yes
context: Genome composition is used to describe the make up of contents of a haploid genome, which should include genome size, proportions of non-repetitive DNA and repetitive DNA in details. By comparing the genome compositions between genomes, scientists can better understand the evolutionary history of a given genome.

qas: question: What two types of organisms have remarkable differences in their genomic composition?

is_impossible: no

question: What type of organizing can be observed in eukaryote genomes?
answers: text: exon-intron
is_impossible: no

question: In what types of eukaryotes is there a large amount of non-coding DNA?
answers: text: mammals and plants
is_impossible: no

question: What should you distinguish between when talking about gene coding?
is_impossible: yes

question: How much of the genome is non-repetitive DNA in eukaryotes?
is_impossible: yes

question: What is a major part of contents structure made of in non-coding regions?
is_impossible: yes

question: What organization feature do prokaryotes have?
is_impossible: yes

question: What area do mammals and plants have differences in?
is_impossible: yes

question: What can the genome also be divided into?
is_impossible: yes

question: What do cells also include?
is_impossible: yes

question: Who pioneered using the DNA structure as a diagnostic tool?
is_impossible: yes
context: When talking about genome composition, one should distinguish between prokaryotes and eukaryotes as the big differences on contents structure they have. In prokaryotes, most of the genome (85–90%) is non-repetitive DNA, which means coding DNA mainly forms it, while non-coding regions only take a small part. On the contrary, eukaryotes have the feature of exon-intron organization of protein coding genes; the variation of repetitive DNA content in eukaryotes is also extremely high. In mammals and plants, the major part of the genome is composed of repetitive DNA.

qas: question: What is an example of an organism that has a portion of its genetic material outside of its chromosomes?

is_impossible: no

question: What do viruses always carry within their structure?
is_impossible: yes

question: Where is additional genetic material found in a virus?
is_impossible: yes

question: What is another word used for genome?
is_impossible: yes

question: What organism has part of its genetic material inside a virus?
is_impossible: yes

question: What do most viruses more complex than plasmids carry?
is_impossible: yes

question: What did Walter Fiers complete in 1996?
is_impossible: yes

question: In what group are tandem repeats in the largest number?
is_impossible: yes

question: What is another word for the total count of chromosomes?
is_impossible: yes
context: Most biological entities that are more complex than a virus sometimes or always carry additional genetic material besides that which resides in their chromosomes. In some contexts, such as sequencing the genome of a pathogenic microbe, "genome" is meant to include information stored on this auxiliary material, which is carried in plasmids. In such circumstances then, "genome" describes all of the genes and information on non-coding DNA that have the potential to be present.

qas: question: What are examples of classes of eukaryotes where genome only refers to the information found in chromosomes?

is_impossible: yes

question: When was The Institute for Genome Research founded?
is_impossible: yes

question: What is the term for the total DNA base pairs in one lower eukaryote?
is_impossible: yes

question: In both sexes of a species what may a properties of genes be?
is_impossible: yes
context: In eukaryotes such as plants, protozoa and animals, however, "genome" carries the typical connotation of only information on chromosomal DNA. So although these organisms contain chloroplasts or mitochondria that have their own DNA, the genetic information contained by DNA within these organelles is not considered part of the genome. In fact, mitochondria are sometimes said to have their own genome often referred to as the "mitochondrial genome". The DNA found within the chloroplast may be referred to as the "plastome".

qas: question: What is the name for the count of all DNA base pairs in a single haploid genome?

is_impossible: no

question: What accounts for the breakdown of the relation between genome size and morphological complexity in higher eukaryotes?
answers: text: repetitive DNA
is_impossible: no

question: What is the term for the total DNA base pairs in one lower eukaryote?
is_impossible: yes

question: What kind of relationship do copies of a haploid genome have with mollusks that isn't effective?

is_impossible: yes

question: What do cells also include?
is_impossible: yes

question: Aside from karyotype, what are other genomic traits studied by scientists?
is_impossible: yes
context: Genome size is the total number of DNA base pairs in one copy of a haploid genome. The genome size is positively correlated with the morphological complexity among prokaryotes and lower eukaryotes; however, after mollusks and all the other higher eukaryotes above, this correlation is no longer effective. This phenomenon also indicates the mighty influence coming from repetitive DNA act on the genomes.

qas: question: What is a name for the reduced complement of genetic material necessary for an organism to live?

is_impossible: yes

question: What is being done on single cell silico?
is_impossible: yes

question: In what two ways are experiments being carried out to understand how genes survive?
is_impossible: yes

is_impossible: yes

question: What are scientists studying to understand how they survive a reduction in silico?
is_impossible: yes

question: What accounts for the breakdown of the relation between genome size and morphological complexity in higher eukaryotes?
is_impossible: yes

question: What do viruses always carry within their structure?
is_impossible: yes

question: Which viral genome did Fiers sequence?
is_impossible: yes
context: Since genomes are very complex, one research strategy is to reduce the number of genes in a genome to the bare minimum and still have the organism in question survive. There is experimental work being done on minimal genomes for single cell organisms as well as minimal genomes for multi-cellular organisms (see Developmental biology). The work is both in vivo and in silico.

is_impossible: yes

question: What is the number of protein-coding genes divided by to get the proportion of non-repetitive DNA?
is_impossible: yes

question: How do you calculate tandem repeats?
is_impossible: yes

question: What is included in virus RNA?
is_impossible: yes

question: What do cells also include?
is_impossible: yes
context: The proportion of non-repetitive DNA is calculated by using the length of non-repetitive DNA divided by genome size. Protein-coding genes and RNA-coding genes are generally non-repetitive DNA. A bigger genome does not mean more genes, and the proportion of non-repetitive DNA decreases along with increasing genome size in higher eukaryotes.

is_impossible: yes

question: Where is additional genetic material found in pathogenic microbes?
is_impossible: yes

question: In higher eukaryotes, what has an inverse relationship with genome size?
is_impossible: yes
context: It had been found that the proportion of non-repetitive DNA can vary a lot between species. Some E. coli as prokaryotes only have non-repetitive DNA, lower eukaryotes such as C. elegans and fruit fly, still possess more non-repetitive DNA than repetitive DNA. Higher eukaryotes tend to have more repetitive DNA than non-repetitive ones. In some plants and amphibians, the proportion of non-repetitive DNA is no more than 20%, becoming a minority component.

is_impossible: yes

question: In what organism is duplication popular?
is_impossible: yes

question: What do chloroplasts have that is referred to as the mitochondrial genome?
is_impossible: yes
context: The proportion of repetitive DNA is calculated by using length of repetitive DNA divide by genome size. There are two categories of repetitive DNA in genome: tandem repeats and interspersed repeats.

question: DNA transposons do not use which genetic material used by Class 1 TEs?
is_impossible: yes

question: What is the first range of genetic novelty?
is_impossible: yes

question: What do most viruses more complex than plasmids carry?
is_impossible: yes
context: Tandem repeats are usually caused by slippage during replication, unequal crossing-over and gene conversion, satellite DNA and microsatellites are forms of tandem repeats in the genome. Although tandem repeats count for a significant proportion in genome, the largest proportion in mammalian is the other type, interspersed repeats.

qas: question: What is the main source of interspersed repeats?

is_impossible: yes

question: What kind of genetic material can be produced from retrotransposons?
is_impossible: yes

question: What is another word used for genome?
is_impossible: yes
context: Interspersed repeats mainly come from transposable elements (TEs), but they also include some protein coding gene families and pseudogenes. Transposable elements are able to integrate into the genome at another site within the cell. It is believed that TEs are an important driving force on genome evolution of higher eukaryotes. TEs can be classified into two categories, Class 1 (retrotransposons) and Class 2 (DNA transposons).

context: Retrotransposons can be transcribed into RNA, which are then duplicated at another site into the genome. Retrotransposons can be divided into Long terminal repeats (LTRs) and Non-Long Terminal Repeats (Non-LTR).

qas: question: What is a term that can describe how DNA transposons move?
answers: text: cut and paste
is_impossible: no

question: DNA transposons do not use which genetic material used by Class 1 TEs?
answers: text: RNA
is_impossible: no

question: What term describes how duplication happens in the genome?
is_impossible: yes

question: What do genome not use as intermediate?
is_impossible: yes

question: What helps metozoan move?
is_impossible: yes

question: In what organism is duplication popular?
is_impossible: yes

question: What does cut and paste help metazoan do?
is_impossible: yes

question: What is the relation between base pairs and the human genome called?
is_impossible: yes

question: Where is additional genetic material found in pathogenic microbes?
is_impossible: yes

question: What do microbes transfer to chloroplasts?
is_impossible: yes
context: DNA transposons generally move by "cut and paste" in the genome, but duplication has also been observed. Class 2 TEs do not use RNA as intermediate and are popular in bacteria, in metazoan it has also been found.

qas: question: What is another word for the total count of chromosomes?
answers: text: karyotype
is_impossible: no

question: Aside from karyotype, what are other genomic traits studied by scientists?
answers: text: genome size, gene order, codon usage bias, and GC-content
is_impossible: no

question: What were other traits besides karyotype studied by Brown in 2002?
is_impossible: yes

question: What is another word for gene order?
is_impossible: yes

question: What does GC-content have that can be measured?
is_impossible: yes

question: Why do researchers calculate the sum of an organisms genes?
is_impossible: yes

question: What are two things that Reese studied about karyotype in 2004?
is_impossible: yes

question: When was The Institute for Genome Research founded?
is_impossible: yes

question: What did Walter Fiers complete in 1996?
is_impossible: yes

question: What is a possible product of duplications?
is_impossible: yes
context: Genomes are more than the sum of an organism's genes and have traits that may be measured and studied without reference to the details of any particular genes and their products. Researchers compare traits such as chromosome number (karyotype), genome size, gene order, codon usage bias, and GC-content to determine what mechanisms could have produced the great variety of genomes that exist today (for recent overviews, see Brown 2002; Saccone and Pesole 2003; Benfey and Protopapas 2004; Gibson and Muse 2004; Reese 2004; Gregory 2005).

qas: question: What type of generation of genetic material has a big part in making the genome what it is?
answers: text: Duplications
is_impossible: no

question: What is a possible product of duplications?
answers: text: genetic novelty
is_impossible: no

question: What role does genetic novelty play in the genome?
is_impossible: yes

question: What is the first range of genetic novelty?
is_impossible: yes

question: What are gene clusters a large part of?
is_impossible: yes

question: How far can genetic novelty go?
is_impossible: yes

question: What is the first example of genetic novelty?
is_impossible: yes

question: What two types of organisms have remarkable differences in their genomic composition?
is_impossible: yes

question: Where are Long terminal repeats duplicated?
is_impossible: yes

question: What is another word used for genome?
is_impossible: yes
context: Duplications play a major role in shaping the genome. Duplication may range from extension of short tandem repeats, to duplication of a cluster of genes, and all the way to duplication of entire chromosomes or even entire genomes. Such duplications are probably fundamental to the creation of genetic novelty.

qas: question: What is an explanation for the resemblance between disparate parts of the genome?
answers: text: Horizontal gene transfer
is_impossible: no

question: In which organisms does horizontal gene transfer appear to occur commonly?
answers: text: microbes
is_impossible: no

question: Parts of which organelle genomes are thought to have ended up in the nucleus of eukaryotic cells via transfer?
answers: text: chloroplast and mitochondrial genomes
is_impossible: no

question: What helps explain why different parts of chloroplasts are similar?
is_impossible: yes

question: In what organism are eukaryotic cells common?
is_impossible: yes

question: What does horizontal gene transfer explain about nuclear chromosomes?
is_impossible: yes

question: Where do microbes transfer material from their chloroplast and mitochondrial genomes?
is_impossible: yes

question: What do microbes transfer to chloroplasts?
is_impossible: yes

question: What are the eukaryotes found in the mitochondria called?
is_impossible: yes

question: In both sexes of a species what may a properties of genes be?
is_impossible: yes

question: What are scientists studying to understand how they survive a reduction in silico?
is_impossible: yes
context: Horizontal gene transfer is invoked to explain how there is often extreme similarity between small portions of the genomes of two organisms that are otherwise very distantly related. Horizontal gene transfer seems to be common among many microbes. Also, eukaryotic cells seem to have experienced a transfer of some genetic material from their chloroplast and mitochondrial genomes to their nuclear chromosomes.
