RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar-phosphate backbone of RNA is broken, cleaving the RNA molecule. RNA is susceptible to this base-catalyzed hydrolysis because the ribose sugar in RNA has a hydroxyl group at the 2’ position. This feature makes RNA chemically unstable compared to DNA, which does not have this 2’ -OH group and thus is not susceptible to base-catalyzed hydrolysis.
