The rna-induced silencing complex
WebbsiRNA (short [or small] interfering RNA) is a class of small double-stranded RNA molecules that silence gene expression by inducing the RISC (RNA-induced silencing complex) to cleave mRNA. What is the average molecular weight of siRNA? For a typical 21mer duplex, it is approximately 13,300.

WebbRNA interference (RNAi) is one of the pathways, collectively named RNA silencing pathways, that employ small RNAs as guides for sequence-specific silencing [reviewed in ( Ketting, 2011 )]. RNAi was discovered in C. elegans and defined as sequence-specific mRNA degradation induced by long double-stranded RNA (dsRNA) ( Fire et al., 1998 ).
