Question

Assertion (A): RNA is unstable and can mutate at a faster rate.
Reason (R): The presence of 2’-OH group in every nucleotide of RNA makes it labile and easily degradable.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

RNA Instability and Mutation Rate

Answer 1

The Correct Option is A

Assertion (A): RNA is indeed more unstable compared to DNA due to the 2’-OH group in its sugar molecule, which makes it more prone to hydrolysis and degradation.
Reason (R): The presence of the 2’-OH group in RNA makes it more reactive, contributing to its instability and higher mutation rate
