RNA interference
RNA interference (RNAi) is a natural cellular process that regulates gene expression. It works by using small RNA molecules to target specific messenger RNA (mRNA) sequences, which carry instructions for making proteins. When these small RNA molecules bind to their matching mRNA, they prevent the mRNA from being translated into protein, effectively silencing that gene. This process plays a crucial role in controlling various biological functions and protecting cells from viral infections and transposons (genetic "jumping" elements). Scientists are exploring RNAi for potential therapies in treating diseases, including cancer and genetic disorders.

RNA interference (RNAi) is a natural cellular process that helps regulate gene activity. When a cell detects specific RNA molecules that correspond to certain genes, it can produce small RNA fragments that bind to those molecules. This binding effectively "silences" the genes, preventing them from making proteins. This process is crucial for controlling gene expression, protecting against viruses, and maintaining cellular health. Researchers are exploring RNAi for potential use in therapies to treat diseases by targeting and silencing harmful genes, offering a promising avenue for medical advancements.
