RNA hydrolysis refers to the breakdown of RNA molecules through the introduction of water molecules. The process involves the cleavage of phosphate bonds and the release of nucleotides from the RNA molecule. There are various synonyms for RNA hydrolysis, including ribonuclease activity, RNA digestion, RNA degradation, RNA cleavage, and RNA breakdown. All of these synonyms refer to the same process of breaking down RNA molecules into smaller constituents. RNA hydrolysis plays a vital role in biological processes such as gene expression and RNA turnover. Researchers and scientists often use these synonyms interchangeably when referring to RNA hydrolysis in their studies.
