Question

The enzyme reverse transcriptase is:

• A. RNA dependent RNA polymerase
• B. RNA dependent DNA Polymerase
• C. DNA dependent DNA polymerase
• D. DNA dependent RNA polymerase

Answer 1

The correct option is B

RNA dependent DNA Polymerase

The correct option is B.

Explanation of the correct option:

1. A reverse transcriptase (RT) is basically an enzyme that is used in the process of reverse transcription and is used to synthesize DNA (circular DNA or cDNA) from RNA.
2. This enzyme reverse transcriptase is available in certain infections that have the hereditary material as the RNA.
3. It is needed for the reverse record of the viral RNA to DNA further which can be embedded into the host DNA.
4. Hence, the enzyme in RNA-dependent DNA polymerase, in which the RNA section is considered as the parent and the cDNA is incorporated.

Final answer: The enzyme reverse transcriptase is RNA-dependent DNA Polymerase.
