Question

In RNA interface, the dsRNA molecule prevents ________

• A. transcription of mRNA
• B. transport of RNA from nucleus to cytoplasm
• C. translation of mRNA
• D. aminoacylation

Answer 1

The Correct Option is C

In RNA interference (RNAi), double-stranded RNA (dsRNA) is processed into small interfering RNAs (siRNAs) by the enzyme Dicer. These siRNAs integrate into the RNA-induced silencing complex (RISC), which then binds to complementary mRNA molecules. 

This binding prevents translation of the target mRNA into protein, effectively silencing gene expression. While dsRNA can theoretically affect other processes, its primary and most well-characterized role in RNAi is to block translation rather than transcription (A), RNA transport (B), or aminoacylation (D).

The correct answer is (C) translation of mRNA.
