Unformatted text preview: 101) If you examined human CD4 + Helper-T cells exposed to the green monkey-adapted vaccine virus, you would NEVER find A) Newly synthesized DNA chromosomes of HIV within CD4 + helper T-cells B) RNA chromosomes from the initial infection of HIV within CD4 + helper T-cells C) DNA chromosomes of HIV inserted into the chromosomes of CD4 + helper T-cells D) Newly synthesized reverse-transcriptase in CD4 + helper T-cells E) All of the above answers are correct 102) If you examined human CD4 + Helper-T cells exposed to the gorilla-adapted vaccine virus, you would NEVER find A) Newly synthesized DNA chromosomes of HIV within CD4 + helper T-cells B) RNA chromosomes from the initial infection of HIV within CD4 + helper T-cells C) DNA chromosomes of HIV inserted into the chromosomes of CD4 + helper T-cells D) Newly synthesized reverse-transcriptase in CD4 + helper T-cells E) Answers C & D are both correct 103) The safest virus with respect to preventing the virus from evolving inside a patient’s body to cause AIDS would be (you can assume that the initial vaccine virus given to a patient is genetically uniform): A) The green monkey-adapted vaccine virus B) The gorilla-adapted vaccine virus C) No expected differences between the green monkey and gorilla vaccine viruses D) Wild type virus E) Both answers B & D are correct 104) Assume (in this problem only) that both vaccines proved to be safe but instead of preventing infection by wild type HIV, they provided only partial protection. Exposure of people to the gorilla-adapted vaccine did not protect them from getting an infection but reduced by 50% the number of HIV’s viruses residing in an infected individual. Exposure of people to the green-monkey adapted vaccine reduced by 50% the number of people getting infected, but in those individuals that did get infected the HIV mutation rate was doubled due to a persistent change in the metabolism of vaccine-exposed CD4 + helper-T-cells. In vaccinated people that became infected with wild type HIV, the time to onset of AIDS symptoms: A) Would be longest in people receiving the green monkey-adapted vaccine B) Would be longest in people receiving the gorilla-adapted vaccine C) Would be shorter in people receiving the green monkey-adapted vaccine compared to infected people not receiving the vaccine D) No difference between the vaccinated groups E) Answers B and C are both correct 105) If vaccinated people were also given AZT, this procedure: A) Would help protect against rare reverse mutations that made the vaccine virus capable of causing disease. B) Would stop gorilla-adapted vaccine from entering the CD4 + helper-T cells C) Would provide a second mechanism preventing the green monkey-adapted vaccine from entering CD4+ helper-T cells D) Answers B and C are both correct E) None of these answers are correct _________________________________________________________________________________________...
