19. Genomics

Segments of eukaryotic DNA that can move from one site to another in the genome by means of an RNA intermediate are called __________.

Once an organism's genome sequence has been determined, how do scientists generally start identifying all the genes within the genome?

What tool or resource is useful for identifying previously unknown protein-coding genes in a genomic DNA sequence?

Multigene families arise as a result of __________.

Who discovered "jumping genes" (transposons)?

How do shotgun techniques differ from previous sequencing methodologies?

An example of a systems biology experiment might be __________.

What factor accounts most for the difference in genome size between vertebrates and prokaryotes?

In the United States, the National Center for Biotechnology Information (NCBI) provides __________.

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?

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 __________.

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?
