Drugs like AZT, ddC, or ddI work against the AIDS virus because they
A)destroy viral proteins.
B)prevent the formation of viral mRNA.
C)block the action of viral tRNA.
D)look like nitrogenous bases and block viral reverse transcriptase.

Question

Quizplus · Accepted Answer

AZT, ddC and ddI are all nucleoside analogs that resemble the structure of the nitrogenous bases found in DNA. When incorporated into the viral RNA during reverse transcription, they halt further DNA synthesis because they lack a 3' hydroxyl group that is necessary for further elongation. This effectively blocks the action of viral reverse transcriptase and prevents the formation of viral DNA.
