In molecular biology mir-320 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms. The biogenesis of miR-320 is different from the canonical microprocessor-dependent miRNAs. The pre-miR-320 is transcribed directly as a precursor microRNA hairpin and thus contains a 5′ m7G-cap.
