RNAse, or ribonuclease, is an enzyme that catalyzes the degradation of RNA molecules. It plays a crucial role in various biological processes, including RNA processing and turnover, by breaking down RNA into smaller components. This helps regulate gene expression and maintain cellular health. There are different types of RNAse, such as RNase A and RNase H, each with specific functions and mechanisms. These enzymes are found in many organisms, including humans, and are essential for cellular metabolism and the proper functioning of the ribosome, where proteins are synthesized.
