<span>siRNA guides the RISC that cleaves the target mRNA. siRNA binds to its target mRNA due to its complementarity.</span> <span>Small interfering RNA (siRNA) has a function in RNA interference, which means it causes gene silencing through repression of transcription. siRNA together with some proteins (like Argonaute) form the RISC. When siRNA recognize the target mRNA it causes degradation of mRNA and thus silencing the gene that encodes that mRNA.</span>
