What is the primary function of ribonucleases (RNase)?

Ribonucleases (RNase) primarily function as enzymes that catalyze the degradation of RNA. This process is crucial for various biological functions, including the regulation of RNA levels within the cell, the removal of defective or unnecessary RNA, and the processing of precursor RNA molecules into their mature forms. By breaking down RNA, RNases play a significant role in maintaining RNA homeostasis and ensuring the proper functioning of cellular processes.

In addition, the degradation of RNA is essential for gene regulation and control of protein synthesis, as it can influence the availability of mRNA for translation. Therefore, the ability of RNases to digest RNA molecules is a fundamental aspect of cellular metabolism, affecting numerous pathways and cellular responses.
