Question
12. Which of the following statements regarding the influenza virus is FALSE?
a. The genome of influenza is very tiny to allow the generation of as many virions as
possible.
b. The influenza genome maximizes gene reassortment.
c. The genome of influenza is well designed for evasion of the immune system.
d. The influenza genome allows for large quantities of virions to be created for continued
infection.
13. Which of the following stages of the influenza infection cycle is inhibited by Tamiflu?
a. the coating of the capsid envelope
b. the assembly of the capsid
c. the cleaving of the host receptor and release of the virus by budding
d. the packaging of viral genome segments and exit from the nucleus
14. Why must influenza have highly efficient host-to-host transmission?
a. because of its rapid infection c. because of genetic reassortment
b. because of its slow infection d. because of latent infection
15. What is the cure for infection with HIV?
a. vaccine c. antiviral drugs
b. radiation d. There is no cure for HIV.
16. A small subset of the human population does not express the CD4 and CCR5 receptors. To what virus are these individuals naturally immune?
a. HIV c. influenza
b. HPV d. hepatitis
Explanation / Answer
12 A
The genome of influenza carry 8 segments of vifal RNA.These 8 RNAs are a total of 14000 nucleotides in length.
13. C
Tamiflu belong to the class of Neuraminidase inhibitors. It blocks the function of viral neuramunidase of the influenza virus by preventing it's reproduction by budding from the host cell.
14 c
The highly effctive transmission is likely due to genetic reassortment as multiple variants were prevalent in the recipient host.
15. D
THere is no cure for HIV
There is no medication or procedure that could free a patient completely from hiv virus or reverse the damage it caused to its immune system
