microRNA
Any of a group of short (generally 21 to 24 nucleotides in length), non-coding RNA molecules which fold upon themselves (“hairpins”) and are usually cleaved from larger hairpin-containing RNA (itself often processed from some portion of mRNA).MiRNA is conserved through evolution and plays a role in RNA interference, destroying mRNA made by specific genes, suppressing gene expression and controlling translation of target mRNAs, thereby regulating critical aspects of plant and animal development.
