Answer 1

QUESTION 67

The enzyme responsible for HIV mRNA transcription is reverse transcriptase. This enzyme is encoded from the genome of the virus and its main function is to transcribe their RNA into a DNA molecule. It is called “reverse” because normally, transcription occurs from DNA to RNA but in the context of retroviruses such as HIV, the process is from RNA to DNA.
