Biology Questions

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “Dicer” cuts dsRNA into smaller fragments called siRNA, which then form a complex with RISC to degrade specific RNA molecules. Can you explain the functions and importance of this process in gene regulation?

Answer

RNA interference serves as a mechanism for regulating genes in eukaryotes. In this process, the enzyme known as “dicer” cleaves double-stranded RNA (dsRNA) into shorter segments referred to as siRNA, which then associate with the RISC complex to target and degrade specific RNA molecules. The siRNA, or small interfering RNA, within the RISC complex identifies and attaches to corresponding mRNA, leading to the cleavage of the mRNA strand. Consequently, this results in the degradation of the targeted mRNA. This process illustrates how RNA interference effectively inhibits translation.
