RNA interference (RNAi) refers to phenomenon that endogenous or exogenous double-stranded RNA (dsRNA) mediate degradation of specific mRNA, which results in silence of target genes and brings about the absence of specific functional phenotype.

• RNA干扰(RNA interference, RNAi)是指内源性或外源性双链RNA(double stranded RNA, dsRNA)介导的细胞内mRNA发生特异性降解，从而导致靶基因的表达沉默，产生相应的功能表型的缺失现象。
