Question: How can comparative genomics assist in the treatment of HIV?

Answer: Understanding the evolution of HIV in an individual will help scientists understand how the virus responds to different drug regimes and will lead to better treatments.

Question: The study of comparative genomics has given researchers the ability to look at multiple genomes from different species, which has lead to new ideas about the evolutionary history of organisms. The conclusion is that
