Question

How does biosynthesis of reverse transcribing viruses occur?

-What enzyme is used?
-What's an example?
-Host or viral encoded?

Answer 1

Reverse transcribing viruses, such as retroviruses, use an enzyme called reverse transcriptase to convert their RNA genome into DNA. One example of a reverse transcribing virus is HIV.

Step-by-step explanation:

Reverse transcribing viruses, such as retroviruses, use an enzyme called reverse transcriptase to convert their RNA genome into DNA. This process is known as reverse transcription. Reverse transcriptase is a viral-encoded enzyme that transcribes an RNA template into DNA. One example of a reverse transcribing virus is HIV, which uses reverse transcription to convert its RNA genome into DNA that integrates into the host cell genome.
