interferenssiRNA
InterferenssiRNA, often shortened to siRNA, is a small double-stranded RNA molecule approximately 21-25 nucleotides in length. It plays a crucial role in the biological process known as RNA interference (RNAi). RNAi is a natural cellular mechanism that regulates gene expression by silencing target messenger RNA (mRNA) molecules.
The process begins when a double-stranded RNA, either endogenous or exogenous, is processed by an enzyme called
Once the siRNA-guided RISC complex binds to the target mRNA, it leads to the degradation of that
