Which of the following types of RNA molecules plays a crucial role in the regulation of gene expression by binding to specific mRNA sequences and preventing their translation?

MicroRNAs (miRNAs) are small non-coding RNA molecules that play a crucial role in the regulation of gene expression by binding to specific mRNA sequences and preventing their translation, whereas tRNA is involved in protein synthesis, rRNA is a component of ribosomes, and snRNA is involved in splicing.
