RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression or translation by neutralizing targeted mRNA molecules. This mechanism is crucial for regulating gene expression and defending against viral infections. It employs small RNA molecules like small interfering RNAs (siRNAs) and microRNAs (miRNAs) to silence specific genes, which has made it an essential tool in molecular biology techniques for studying gene function and developing therapeutic strategies.
