Dicer bound to microRNA precursor, illustration

---

Illustration of the dicer-2 enzyme (bottom) from a fruit fly (Drosophila melanogaster) bound to a synthetic double-stranded RNA (ribonucleic acid, red) molecule. Dicer processes double-stranded RNA to produce short single-stranded RNA molecules that act to inhibit the expression of specific genes by regulating the expression of messenger RNA (mRNA).
