Question
Answer the following and inlcude the references
- 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?
- Do you think that ART combinations/options might help in suppressing the viral replication of SARS-CoV-2? Expound.

The whole world right now is concerned (or they should be) about the appearance of new variants of SARS-CoV-2. Among other things, these variant viruses have mutations that change the amino acid sequence of the spike protein on the virus surface. While this is concerning, I would like to propose that there is a limit to how far these mutations can change the spike protein. Why can't there be an endless number of new mutations of this viral protein? How would these amino acid changes affect how the virus works?arrow_forward
