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?
More Viral Morphology and Diversity Questions:
What material is the capsid made out of?
Three main features include
nucleic
acid (DNA or RNA),
capsid
(or the protein shell), and the
envelope
(which is a layer of the membrane - on only some viruses).
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?
The virus expresses a miRNA that specifically targets a tumor suppressor gene
The virus expresses a gene that activates the host cells survival and proliferation pathway

On the left (below) is an experimental drug, which is a nucleoside analogue. On the right is adenosine. The drug is used to treat RNA viruses (viruses that have RNA rather than DNA as their genetic material), such as Ebola. How do you think this works?
