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. 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 …
