Some RNA-dependent RNA-polymerase enzymes make a lot of mistakes. Why would this work to the advantage of a virus in terms of how effective a vaccine might be?

NEED ASAP THANK YOU

Truth about harm of COVID vaccines

NEED ASAP THANK YOU

If you Infect the Jurkat T lymphocyte cell line with HIV-1 strain IIIB. Lyse the infected cells at the peak cytopathic effect and isolate DNA from the whole cell lysates. 1. What types of PPE will be used in this experiment? 2. Is this experiment using a recombinant DNA? 3.will workers require health surveillance?

What are some ways that viruses have evaded our immune system? Include source used. Thank you

1. Complete the table Genome type Capsid Envelope Transmission Viral replication occurs in The virus can/cannot integrate into the cell genome Name viral enzymes located in the central core Prevention. If not exist, explain why The viral envelope is formed from.. HIV HPV

1.Which of the following statements is true? Vaccines cannot be made against viruses. Viruses are big enough to be seen with a light microscope. Viruses need to infect host cells to make copies of themselves. Viruses have organelles such as a nucleus. 2.Which type of movement across membranes is used by COVID-19 to infect cells? Active Transport Simple Diffusion Facilitated Diffusion Endocytosis
