RNA interference (RNAi)

RNA interference (RNAi) is a natural cellular process that regulates gene expression by使用 small RNA molecules to silence specific genes. When a gene is to be turned off, a short double-stranded RNA called siRNA or miRNA binds to the target messenger RNA (mRNA), marking it for destruction or blocking its translation into a protein. This prevents the gene from producing its protein product. RNAi is a crucial mechanism in controlling gene activity, defending against viruses, and has potential therapeutic applications for diseases caused by abnormal gene expression.
