RNA

RNA, or ribonucleic acid, is a vital molecule in all living cells. It acts as a messenger, carrying information from DNA—the genetic blueprint of organisms—to the machinery that makes proteins, which perform most life functions. Unlike DNA, which is double-stranded and stable, RNA is typically single-stranded and can change its shape to perform various roles, including helping in protein synthesis and regulating gene expression. In essence, RNA plays a crucial role in translating genetic information into the proteins that make up our bodies and support life processes.
