Diagram illustrates the various stages of the miRNA biogenesis pathway, including both the usual and alternative routes. Beginning with the transcription of primary miRNAs by RNA polymerase II/III, the process involves the involvement of the Drosha–DGCR8 complex and Dicer. Ultimately, mature miRNAs are produced and are responsible for controlling gene expression through the action of the miRISC
