The complete coronavirus genome sequence from the first known patient infected with SARS-CoV-2 was published on January 10th 2020, just a short time after the patient had been hospitalized in China with respiratory symptoms. They did this so quickly using nanopore sequencing. Scientists compared the genome sequence from the new coronavirus (SARS-CoV-2) with the genome sequences from several other coronaviruses and they did identify a sequence unique to the SARS-CoV-2 strain. This unique sequence was in the N gene of the viral genome.
What protein is made from the N gene of the virus?
What is an emerging virus? Give two examples. Propose an experiment to explain how an emerging virus could arise.
Please introduce how to obtain a nucleotide sequence of unknown viruses. Please give me a detailed process.

- You have isolated a new virus that you want to classify using the Baltimore approach to classification. However, you don’t have much to work with. Just an agarose gel, ethidium bromide to strain the nucleic acid on the gel, and a set of enzymes. Assume you have pure virus. Enzyme A digests ssDNA, Enzyme B digests all DNA, and Enzyme C digests ssRNA. Base hydrolysis digests all RNA. You run a gel and get the results below after staining with ethidium bromide: From these results, what type of genome do you think the virus has? Briefly explain your answer.arrow_forwardTransmission studies suggest that there are at least three (3) different variants of the SARS-CoV-2 virus circulating in Latin America and the Caribbean. Discuss a recombinant DNA technology strategy that could be used to verify this claim.arrow_forwardAnswer the following regarding the varicella-zoster virus: a) the biology of the virus ( type: DNA/RNA type: single or double stranded) b) how it replicates c) life cycle of the virus (binding, fusion, reverse transcription, integration, replication, and assembly)arrow_forward

- 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.
