Small RNA (sRNA) are polymeric RNA molecules that are less than 200 nucleotides in length, and are usually non-coding. RNA silencing is often a function of these molecules, with the most common and well-studied example being RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA.

WebSep 21, 2024 · Small interfering RNA (siRNA), also known as short interfering RNA or silencing RNA, is a type of double-stranded RNA molecules that function within the RNA interference (RNAi) pathway. It inhibits translation, hence inhibiting the expression of certain genes with complementary nucleotide sequences, by degrading mRNA after transcription.
