base catalyzed hydrolysis rna
This happens because the ribose sugar in RNA contains a hydroxyl (OH) group at the 2' position.
DNA does not have this feature and thus is not susceptible to hydrolysis, making it a more stable molecule.
What is the base hydrolysis of RNA?
The hydrolysis occurs at the phosphodiester bond of the backbone.
Hence, RNA rapidly hydrolyzes in an alkaline environment into cyclic 2',3'-monophosphate nucleotides, which undergo further hydrolysis in water to form a mixture of 2'- and 3'-nucleoside monophosphates.
What is the hydrolysis product of RNA?
RNA and DNA are nucleic acids which on complete hydrolysis yield a pentose sugar, phosphoric acid and nitrogen containing heterocyclic compounds called bases.
What is the purpose of using 1% NaOH in RNA hydrolysis?
When RNA is treated with NaOH, the base catalyzes the cleavage of the phosphodiester bonds between the nucleotides, resulting in the release of individual nucleotides. 3.
Using a 1% NaOH solution provides a controlled environment for RNA hydrolysis.
