"WebSmall interfering RNA ( siRNA) [1] is a class of double-stranded RNA molecules, 20-25 base pairs long. siRNA plays many roles, but it is most notable in the RNA interference (RNAi) pathway, [2] where it interferes with the expression of certain genes. Genes are only affected if they have nucleotide sequences complementary to those of the siRNA. " - Small rna wikipedia
