Micro RNA (miRNA) are a class of small (22 nucleotide in the mature form) non-coding RNA. They are present in plants and animals and function as transcriptional and post-transcriptional regulators of genes. They bind to a complementary region in the transcribed gene to form doublestanded RNA molecules. These are silenced since they cannot be translated and often subsequently degraded by the cell.
