RNA interference (RNAi) is a crucial biological process that plays a vital role in regulating gene expression at the transcriptional and translational levels. It involves the inhibition of gene expression through the degradation of target messenger RNA (mRNA) molecules. This mechanism is mediated by small, double-stranded RNA molecules known as interfering RNAs. Scientists have harnessed this natural mechanism for a variety of applications, including gene therapy, drug development, and basic research.
The fundamental steps in RNAi involve the synthesis of siRNAs from a double-stranded RNA precursor, the formation of the siRNA to an enzyme complex called RISC (RNA-induced silencing complex), and the specific targeting of mRNA molecules by RISC. This leads to the degradation of target mRNAs, thereby inhibiting protein synthesis from those genes.
RNAi has emerged as a versatile tool for analyzing gene function and its implications in various biological processes.
It offers a unique opportunity to manipulate gene expression with high specificity, making it an invaluable resource for researchers across diverse fields of study.
