RNA interference represents a common biological phenomenon of double-stranded RNA mediated post-transcriptional gene silencing, which lies in altitude plants and animals. The mechanism of this process is described as that: the dsRNA in cells are cut into double-stranded small interfering RNA. By joining with an effector complex termed RISC (RNA-induced silencing complex), siRNA binds to the cellular RNA with homologous sequences, and contributes to the degradation of the corresponding mRNA, the inhibition of specific gene expression.

Different from the siRNAs or miRNAs, which are derived from double-stranded or short-hairpin RNA precursors, piRNAs are derived from single-stranded RNA precursors or two non-overlapping and divergently transcribed precursors without the involvement of Dicer endonucleases.

Although the specific mechanism is poorly understood, it is known that the ribonuclease enzyme Dicer binds to and cleaves short double-stranded RNA molecules to produce double-stranded fragments of 21-23 base pairs with two-base single-stranded overhangs on each end.
