Glossary Term MicroRNA
Definition MicroRNAs (miRNAs) are a group of noncoding RNA molecules, generally 21 to 24 nucleotides in length, which are usually cleaved from a larger hairpin-containing RNA (itself often processed from some portion of mRNA). miRNAs are conserved through evolution, and their abundance and expression patterns are suggestive of diverse regulatory roles.
