RNA-guided RNA methylation

RNA-guided RNA methylation is a biological process where small RNA molecules direct specific chemical modifications, called methylation, to target RNA molecules. This process involves guide RNAs recognizing particular sequences in the target RNA and recruiting enzymes that add methyl groups. Methylation can influence RNA stability, structure, and function, playing key roles in gene regulation and cellular responses. It’s a precise, targeted way cells modify RNA to control how genes are expressed, ensuring proper cellular function and adaptation.
