Question

27. Which of the following combinations would you expect to find in an individual who has been diagnosed with AIDS? (A) CD4 cell count below 200 and high viral load. (B) Low levels of HIV antibodies and low viral load. (C) Low viral load and high levels of Gp 120 antibodies. (D) High CD4 count and high viral load. 28. What is the role of HIV viral integrase? (A) It must cut the host DNA to splice in viral DNA. (C) It is needed by the reverse transcriptase. (B) It stabilizes the viral DNA. (D) It is required for viral maturation

Answer 1

27. Option A is correct as when  CD4 count goes below the 200, and there is high viral laod then we can expect the individual  gto be diagnosed with AIDS. The normal count for the CD4 cells is 500 to 1500.

28. HIV uses the integrase to insert its viral DNA in the DNA of host CD4 cell
