You are studying a virus that infects mammals. You are specifically interested in whether the virus frequently jumps from one mammal species to another or whether different strains remain specific to certain hosts over evolutionary time. How could you use phylogenetic methods to test this?

A virus with a narrow host range: a-All of these choices are correct. b-is usually highly virulent. c-infects plants and bacteria but not animals. d-is likely a retrovirus. e-infects cells of only a few species.

49.Comparing the HIV virus to the phages discussed in class... Select one: a. Phages can infect eukaryotes broadly, while HIV infects humans alone b. Both HIV and phages are encapsulated viruses that have phospholipid membranes surrounding their protein capsids c. HIV uses glycosylated, host-derived proteins, while phages use protein spikes, to interact with their host cells facilitating infection d. In the extracellular space, both HIV and phages utilize DNA as their genetic material e. HIV and virulent phages are capable of integrating into their respective host's...

HIV is a retrovirus (a virus that uses reverse transcriptase). a. What is reverse transcriptase? b. How is a retrovirus different from other viruses? c. How does a retrovirus infect a cell and reproduce itself? 2. Review of the immune system. a. What is a T cell? b. What varieties of T cell exist? How are they functionally different? c. What are their roles in the human body? d. How is each T cell variety differentiated from the others (molecularly)?...
QUESTION 1 3 po HIV predominantly infects T-helper cells, cells that are responsible for coordinating B- and T-cell activity. Based on this information, explain why HIV-infected individuals are at a very high risk for developing microbial infections. List the causative agent (virus) and discuss its properties. Name and briefly discuss 3 diseases that AIDS patients are more likely to contract.
