Multiple Choice
Use the following information to answer the questions below.
HIV's genome of RNA includes code for reverse transcriptase (RT) , an enzyme that acts early in infection to synthesize a DNA genome off of an RNA template. The HIV genome also codes for protease (PR) , an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. Both RT and PR represent potential targets for antiretroviral drugs. Drugs called nucleoside analogs (NA) act against RT, whereas drugs called protease inhibitors (PI) act against PR.

A) extra genes by gene duplication events.
B) chromosomal translocation.
C) genetic variation by mutations.
