Which explanation is one of the reasons for the ability of the influenza virus to evolve rapidly? Its ability to integrate into the host genome allows it to remain in host cells for long periods of time. The virus may undergo antigenic shift when multiple strains infect the same organism. It can convert its RNA genome into a DNA copy by using the enzyme reverse transcriptase. Its single-stranded DNA genome is sensitive to environmental factors that create mutations.

11. Segmented influenza RNA genomes are capable of a. reverse transcription. c. reassortment. b. cell fusion. d. proviral transposition. 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?

which of the following is not an advantage that a large genome provides to a virus? 1- often a single large genome virus can infect multiple host species while most small genome viruses can only infect a single host species. 2- large genome viruses can evade the immune system better 3- large genome viruses can evade the immune system better
Both the human immunodeficiency (HIV) and influenza virus are RNA viruses. Most otherwise healthy people will recover from an influenza infection in 3-7 days. HIV on the other hand is a lifelong infection. What is the explanation for this difference? HIV virus undergoes reverse transcription an integrates into the host genome. HIV virus can use the host translation machinery to make more viral particles very quickly. HIV virus infects the immune cells and is more difficult to fight. HIV has a very high mutation rate and shows rapid evolution.
