RNA
RNA (ribonucleic acid) is a single-stranded nucleic acid with ribose and uracil that carries genetic information, catalyzes reactions, and regulates genes; classes include mRNA, tRNA, rRNA, and microRNA, and 27 RNA therapeutics were FDA-approved as of August 2026.
RNA elements and technologies
RNA elements are sequences and structures within an RNA molecule that regulate or catalyze that same molecule without proteins, including metabolite-sensing riboswitches and ribozymes, the catalytic RNAs discovered in 1982.
