Question

The genetic material in retroviruses are

• A. RNA
• B. ssDNA
• C. dsDNA
• D. ds circular DNA

Hint:

Retroviruses are RNA viruses that carry reverse transcriptase enzyme for replication.

Answer 1

The Correct Option is A

Step 1: Understanding retroviruses.
Retroviruses, such as HIV, are RNA viruses that use reverse transcriptase to synthesize DNA from their RNA genome.
Step 2: Identifying the genetic material.
Their genetic material is single-stranded RNA, which is reverse transcribed into DNA inside the host cell.

Final Answer: \[ \boxed{\text{RNA}} \]
