Although 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 __________.

Studies that determine gene annotation __________.

The human genome is thought to contain about how many genes?

The number of genes in an organism's genome is not a perfect indication of the organism's complexity because __________.

Why might the number of genes in eukaryotic genomes underestimate the number of different proteins that an organism makes?

There 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?

The eukaryotic genome is much less tidy and compact than the genomes of prokaryotes. Eukaryotes, but not prokaryotes, have __________.

Alu elements __________.

Recall 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?
