Non-coding RNAs (ncRNAs) are RNA molecules that are not translated into proteins. Various types of ncRNAs, such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and small interfering RNAs (siRNAs), play crucial roles in gene regulation. Unlike messenger RNAs (mRNAs), which serve as templates for protein synthesis, ncRNAs function in diverse cellular processes, including the regulation of gene expression, maintenance of genome integrity, and modulation of cellular responses to environmental changes.
