Earning a Nobel prize for Andrew Fire and Craig Mello, FTP name this naturally occurring gene silencing process also used by biologists to inhibit gene expression, often using micro RNA or siRNA.
It regulates the expression of cis-Nat genes in Arabidopsis, and its failure is the cause of the FMR1 mutation in fragile X syndrome.  Drosha and Pasha are proteins that disrupt exportin-mediated transport involved in this process, which leaves behind subcomponents that bind to foreign molecules and targets them for the RDE-1 nuclease.  Dicer cuts out the stem and loop structure of the double strand precursor to create a single strand template used by the RISC complex to repress translation or destroy messenger templates.
