Question

Reverse transcriptase is

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

Answer 1

The correct option is A RNA-dependent DNA polymerase

Reverse transcriptase, also called RNA-dependent DNA polymerase, is an enzyme that catalyses the reverse transcription of RNA (ribonucleic acid) into DNA (deoxyribonucleic acid).

This catalysed transcription is the reverse process of normal cellular transcription of DNA into RNA, hence the name reverse transcriptase.
