Which of the following types of RNA molecules plays a crucial role in the regulation of gene expression by binding to specific messenger RNA molecules?

A Transfer RNA (tRNA)
B Ribosomal RNA (rRNA)
C MicroRNA (miRNA) ✓
D Small nuclear RNA (snRNA)

Explanation

MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression by binding to specific messenger RNA (mRNA) molecules, thereby preventing their translation into proteins.
