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. WebSmall interfering RNAs (sometimes called silencing RNAs) interfere with the expression of a specific gene. They are quite small (20/25 nucleotides) double-stranded molecules. Their …
