Multiple ChoiceWhy might the number of genes in eukaryotic genomes underestimate the number of different proteins that an organism makes?
Multiple ChoiceAlthough it contains roughly the same number of genes as the nematode genome, the human genome is thought to produce greater phenotypic diversity by means of __________.
Multiple ChoiceThere is about 1,000 times as much DNA in a human cell as in an E. coli cell but only about 5 times as many genes. What accounts for this discrepancy?
Multiple ChoiceThe eukaryotic genome is much less tidy and compact than the genomes of prokaryotes. Eukaryotes, but not prokaryotes, have __________.
Multiple ChoiceRecall that the human genome contains roughly 3 billion base pairs per haploid genome and that about 25% of the human genome is associated with genes, including introns and regulatory sequence. What would be the approximate average length of DNA per human gene if the genome contained 20,000 genes?
Multiple ChoiceSegments of eukaryotic DNA that can move from one site to another in the genome by means of an RNA intermediate are called __________.
