Question

The enzyme reverse transcriptase:

• A. Joins RNA-RNA fragments
• B. Makes a copy of DNA from an RNA molecule
• C. Removes terminal phosphates from 5’ end
• D. Cleaves RNA at random positions

Hint:

Reverse transcriptase works ”in reverse” by copying RNA into DNA.

Answer 1

The Correct Option is B

Reverse transcriptase is an enzyme that synthesizes complementary DNA (cDNA) from an RNA template. This process is a key step in the life cycle of retroviruses like HIV.
