Example Questions

Example Question #1 : Help With Viral Genomics

Which of the following is true about viral genomes?

Possible Answers:

Viral genomes typically consist of 20,000+ genes

Viral genomes are incapable of undergoing recombination events

Viral genomes are always circular

Viral genomes can be either RNA or DNA

Correct answer:

Viral genomes can be either RNA or DNA

Explanation:

The human genome contains 20,000-25,000 genes, so, as one might expect, viral genomes are typically much smaller than this. Viral genomes can either be circular or linear, and both formats are susceptible to recombination events.

Different classes of viruses have different nucleic acid genomes. Double-stranded DNA, single-stranded DNA, double-stranded RNA, and single-stranded RNA can all be found in certain virions.
