Answer to Question 1

Ans:
D

Feedback:

Reverse transcriptase inhibitors inhibit HIV replication by acting on the enzyme reverse transcriptase. Non-nucleotide reverse transcriptase inhibitors block the copying of RNA into DNA. Entry inhibitors, protease inhibitors, and integrase inhibitors do not address this aspect of the HIV replication cycle.

Answer to Question 2

Ans:
A, B

Feedback:

The primary function of cytotoxic T (CD8) cells is to monitor the activity of all cells in the body and destroy any that threaten the integrity of the body. The CD8 cells destroy target cells by releasing cytolytic enzymes, toxic cytokines, and pore-forming molecules or by triggering membrane molecules and intercellular apoptosis. Removal of foreign material from lymph before it enters the blood is the function of lymph nodes.
