Q. Explain in brief one measure for prevention of AIDS?

Q. HIV, the virus that causes AIDS, has a genome that includes the code for reverse transcriptase, an enzyme that can create a DNA genome using an RNA template. The HIV genome also includes a code for protease, an enzyme that cuts long viral polypeptides into smaller, functional proteins.
Drugs called nucleoside analogs act against reverse transcriptase and drugs called protease inhibitors act against protease.
Which of the following treatments is least likely to produce a drug-resistant strain of HIV in a patient?

1. Slowly increasing the dose of a single protease inhibitor over the course of two weeks.
2. Using high doses of both protease inhibitors and nucleoside analogs at the same time for a period of one day to avoid the effects of chemical toxicity in the patient's body.
3. Using a series of nucleoside analogs, one at a time, and changing them every two weeks.
4. Using moderate doses of nucleoside analogs and two different protease inhibitors at the same time for several months.
