How RNAi Works

Assembly of RISC

The small interfering RNAs bind to several proteins.

The RNA and bound proteins form an assembly called the RNA-induced silencing complex, or RISC.

Round shapes labeled proteins are next to a double strand labeled s-i-R-N-A. An arrow points to an assembly of R-I-S-C which shows them all together.
