Q.131) Silencing of specific mRNA is possible via RNAi because of

A) Non-complementary SSRNA

B) Complementary dsRNA

C) Inhibitory SSRNA

D) Complementary tRNA

Answers (1)

best_answer

RNA interference (RNAi) works by introducing double-stranded RNA (dsRNA) that is complementary to the target mRNA. This triggers the silencing of the target gene by degrading its mRNA or preventing its translation. The complementary dsRNA is recognized by the RNA-induced silencing complex (RISC), which leads to the degradation of the target mRNA.

Hence, option(2) is correct.
