Regulatory RNA

Regulatory RNA refers to small RNA molecules that play a crucial role in controlling gene expression within cells. Unlike messenger RNA, which carries instructions for making proteins, regulatory RNAs can turn genes on or off, fine-tuning how much protein is produced. This regulation is essential for many processes, such as cell growth, development, and response to stress. Key types of regulatory RNAs include microRNAs and small interfering RNAs, which help silence genes or prevent their expression. By managing gene activity, regulatory RNAs help maintain cellular functions and overall health.
