Multiple Choice

The following questions refer to the following paragraph.
HIV's genome of RNA includes the 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.
-Every HIV particle contains two RNA molecules. If two genes from one RNA molecule become detached and then, as a unit, get attached to one end of the other RNA molecule within a single HIV particle, which of these is true?

• A) There are now fewer genes within the viral particle.
• B) There are now more genes within the viral particle.
• C) A point substitution mutation has occurred in the retroviral genome.
• D) The retroviral equivalent of crossing over has occurred, no doubt resulting in a heightened positive effect.
• E) One of the RNA molecules has experienced gene duplication as the result of translocation.
