This interactive activity from NOVA scienceNOW illustrates the function of RNA interference (RNAi), a mechanism by which cells interrupt the process of protein synthesis. By effectively silencing genes, RNAi helps to fight infections. Scientists hope that one day they will be able to use this powerful mechanism in the treatment of a wide variety of genetic diseases.
