- Answer the following 1.Are viruses living or non-living organisms? 2. What is the difference between HIV and AIDS? 3. HIV is classified as a retrovirus. What are retroviruses? 4. In your own words, provide a short summary of the HIV replication cycle. 5. Why is reverse transcriptase an important enzyme in the replication cycle of HIV? 6. In the chapter about enzymes, we have discussed how drugs are basically inhibitors. There are currently a multitude of Antiretroviral therapy (ART or ARV) options available to people living with HIV (PLHIV) so that the viral replication is suppressed and does not progress to AIDS. What do you think these drugs target? Discuss briefly. 7. SARS-CoV-2, the virus that causes CoVid-19, belongs to the Coronaviridae family. Viruses under this family have a genome made of single-stranded positive-sense RNA. Is this similar to the viral genome of HIV? If so, do you think that – in theory – they would have similar replication cycles? 8.

Viruses consist of DNA or RNA surrounded by a protein coat called a capsid. The common cold, influenza, chicken pox, warts, AIDS, measles, and covid-19 are all caused by viruses.
