- 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.

- Can i get a help answering this question: The case study tells you that the HIV virus exits the cell by budding, but how can you tell that just based on the structure of the HIV virus? (see attached for the case study)Viruses are host-specific, meaning they can only infect specific types of host organisms. For examble, the adenovirus is responsible for the common cold in humans but your dog can't catch a cold from you. Why is this? The proteins on the virus surface can only bind with proteins on the correct host surface. It is an enveloped or non-enveloped virus. The enzymes carried by the virus are compatible with the host. The genome of the virus is made of DNA or RNA.Describe the biosynthesis Filovirus (Marburg virus genome. Discuss the transcription of the virus genome into new virion particles. If you have an RNA virus you cannot just work in a DNA cell as you don’t have the correct enzymes to make more RNA from RNA. include if Filovirus (Marburg virus must package any special enzymes in order to be effective.
