The HIV virus has an RNA genome but is classified as a retrovirus because viral enzymes reverse transcribe the viral RNA into DNA that inserts into the host genome. A molecule called AZT is a nucleoside mimic often used as an antiviral drug against this step in HIV's replication cycle. Which statement below best describes how HIV might evolve resistance to AZT?
What material is the capsid made out of?
Viruses have been shown to be related to cancer when they get incorporated into the genome of host cells. Which of the following is most likely to result in uncontrolled cell growth?
