Which RNA molecule is expressed in the genome to regulate gene expression?
A) RNAi
B) snoRNA
C) miRNA
D) siRNA

Question

Quizplus · Accepted Answer

miRNA is a type of non-coding RNA that plays a crucial role in regulating gene expression. It achieves this by binding to mRNA molecules, thereby preventing their translation or promoting their degradation. This post-transcriptional regulation allows cells to fine-tune the expression of their genes, making it essential for many biological processes. While RNAi and siRNA are also involved in gene regulation, miRNA is the RNA molecule primarily expressed in the genome for this purpose. SnoRNA, on the other hand, is involved in processing other RNA molecules and modifying their chemical structure, but not in gene regulation.
