More Viral Infections & Hosts Questions:
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?
Which of the following best describes how the Human papillomavirus can cause cervical cancer without causing mutations in any coding regions?
Briefly describe the lytic cycle of a virus.
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
Which of the following best describes how the Human papillomavirus can cause cervical cancer without causing mutations?

Viral Evolution
Which of the following statements is TRUE regarding the use of antiviral therapies?
Why are viruses not considered to be alive?
i. They cannot reproduce on their own
ii. They lack the metabolic machinery to provide energy for themselves
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?
