A nucleic acid involved in gene expression and regulation.
RNA is usually single-stranded and contains ribose sugar and the bases adenine, uracil, guanine, and cytosine. It functions as a messenger, structural component, catalyst, or regulator in many biological processes. Major RNA types include mRNA, tRNA, rRNA, miRNA, siRNA, and lncRNA, each contributing to transcription, translation, RNA processing, and gene regulation.
