NEET 2025, Biology Q41: Recombinant DNA Technology

NEET2025Biology
Q.

Silencing of specific mRNA is possible via RNAi because of

  1. A

    Non-complementary ssRNA

  2. B

    Complementary dsRNA

  3. C

    Inhibitory ssRNA

  4. D

    Complementary tRNA

Solution

RNA interference (RNAi) is a eukaryotic cellular defence mechanism. A complementary double-stranded RNA molecule binds to the specific target mRNA, preventing its translation — effectively silencing that mRNA.
