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.

Let's imagine you have discovered a new RNA virus and found a cell line to grow the viruses (lucky you!). Early experiments show virus' genome to be single-stranded RNA but you are unsure if it is positive or negative RNA. Explain how using anisomycin, an eukaryotic protein synthesis inhibitor, could potentially provide an answer.
Which viruses have potential for the highest mutation rates, DNA or RNA viruses? Explain O DNA viruses as DNA polymerases do not proofread thus make many mistakes/mutations when viral RNA is copied DNA viruses as DNA polymerases do not proofread thus make many mistakes/mutations when viral DNA is copied RNA viruses as DNA polymerases do not proofread thus make many mistakes/mutations when viral DNA is copied RNA viruses as RNA polymerases do not proofread thus make many mistakes/mutations when viral RNA is copied and DNA polymerases do proof read

The dUTPase enzyme is used by the African swine fever virus to repair its own DNA, as the cells the virus infects in swine do not express the dUTPase protein. Which of the following is a reasonable explanation for the role of the dUTPase in the virus lifecycle? Explain your choice in 25 words or less. The dUTPase is necessary to remove dUTP from the viral genome, as uracil should not be present in DNA The dUTPase is necessary to remove dUTP from the viral genome, as uridine cannot correctly base pair with adenine-containing bases The dUTPase is necessary to remove dUTP from the viral genome, as uridine has the wrong sugar component for building DNA More than one of the above answers is correct None of the above answers is correct

O After a retrovirus attaches to the host cell, it injects its viral DNA and uses the host cell's machinery and materials to replicate. O After a retrovirus injects its viral RNA into a host cell, it forms a DNA strand by reverse transcription.

Need help Your friend wants to make a mutation to disable the ACE2 gene (this gene encodes the protein that SARS-CoV-2 uses to enter human cells) in cultured human cells but doesn’t know how. Explain to her how she could use CRISPR to do this. You answer should explain how the ACE2 gene is targeted, cut, and mutated.
Some DNA vaccines use a brief and small electrical shock to get DNA in plasmids into cells. What advantage would there be in using DNA vaccines that consist of plasmids instead of just pieces of double-stranded DNA? The new Covid19 vaccine produced by two companies (Pfizer, Moderna) uses mRNA coding for part of the spike protein of the virus. The virus uses the spike protein to invade human cells where it replicates. Is it surprising that the mRNA must be stabilized with chemicals that need ultra-cold or frozen storage to protect the mRNA from degradation before it causes human muscle cells to make the spike protein? Why not just inject the double-stranded cDNA that codes for the spike protein of the virus? What additional step or steps would you need to use to get the human muscle cells to produce the spike protein if the cDNA was injected to serve as the virus?
