Question

Which one of the following enzyme is responsible for the synthesis of DNA from RNA?

• A. DNA polymerase
• B. RNA polymerase
• C. Reverse transcriptase
• D. DNA ligase

Answer 1

The correct option is C Reverse transcriptase

Reverse transcriptase is responsible for the synthesis of DNA from RNA. A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. It is mainly associated with retroviruses. A retrovirus converts single-stranded genomic, RNA into double-stranded cDNA which can integrate into the host genome, potentially generating a long-term infection that can be very difficult to eradicate.

So, the correct answer is option C.
