Small interfering RNAs

Small interfering RNAs (siRNAs) are short strands of genetic material that play a crucial role in regulating gene expression. They are involved in a process called RNA interference, where they help silence specific genes by binding to messenger RNA (mRNA) molecules, preventing them from producing proteins. This mechanism acts like a cellular control system, allowing cells to manage the amount of proteins being made, which is essential for various biological processes, including development, defense against viruses, and maintaining cellular functions. siRNAs have also gained attention for their potential use in medical therapies to target and silence harmful genes.
