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.

RNAi技术是双链RNA(double strand RNA，dsRNA)介导的序列特异性的转录后基因沉默，广泛存在于高等植物和动物中，其机制是细胞内的dsRNA被Dicer剪切成双链的小分子干涉RNA (small interfering RNA，siRNA)与RNA诱导的基因沉默复合物结合，降解与之互补的靶mRNA，特异性抑制靶基因表达。
