Question:

What is the role of reverse transcriptase in recombinant DNA technology?

Show Hint

Reverse transcriptase is crucial for converting RNA into DNA, a fundamental step in gene cloning and cDNA library construction.

Updated On: Sep 20, 2025

It leaves RNA at specific sequences
It synthesizes DNA from an RNA template
It repairs damaged DNA
It unwinds DNA during replication

Verified By Collegedunia

The Correct Option is B

Solution and Explanation

Step 1: Understand the function of reverse transcriptase.
Reverse transcriptase is an enzyme that synthesizes DNA from an RNA template. This process is essential in recombinant DNA technology, especially when creating complementary DNA (cDNA) from RNA.
