Which of the following statements correctly describes how RNA interference (RNAi) reduces the expression of selected genes?
A) Synthetic double-stranded RNA molecules stop transcription from occurring.
B) Synthetic single-stranded RNA molecules trigger incorrect processing of pre-RNA into RNA.
C) Synthetic double-stranded RNA molecules trigger the breakdown of a gene's messenger RNA.
D) Synthetic single-stranded RNA molecules bind cellular RNA and block translation.

Question

Quizplus · Accepted Answer

Synthetic double-stranded RNA molecules introduced into a cell can trigger the RNA interference (RNAi) pathway, leading to the degradation of messenger RNA (mRNA) molecules that have sequences complementary to either strand of the introduced RNA. This process effectively reduces the expression of the targeted gene by preventing its mRNA from being translated into protein.
