Definition: A small RNA molecule that is the product of a longer exogenous or endogenous dsRNA, which is either a bimolecular duplex or very long hairpin, processed (via the Dicer pathway) such that numerous siRNAs accumulate from both strands of the dsRNA. siRNAs trigger the cleavage of their target molecules.
Synonyms: INSDC_qualifier:siRNA, small interfering RNA, INSDC_feature:ncRNA
