Up to the present only methods of enzymatic nature have been available for the specific partial hydrolysis of the nucleic acid chain such as treatment with pancreatic ribonuclease (RNase)

What is the hydrolysis of nucleic acids?

HYDROLYSIS OF NUCLEIC ACIDS 2015-043631 1Department of Biology, College of Science, University of the Philippines Baguio March 14, 2019 ABSTRACT Nucleic acids namely, RNA and DNA both undergo the process of hydrolysis producing products such as phosphates, pentose sugars and heterocyclic bases.

How is the glycosidic bond of DNA and RNA hydrolyzed?

The glycosidic bond of DNA and RNA is hydrolyzed by acids. In acid hydrolysis, the purine acid has been added. This phenomenon occurs both in DNA and RNA. The order of stability where d stands for DNA while r stands for RNA.

Which hydrolysate is more susceptible to hydrolysis than DNA?

For test for purine bases, acid hydrolysates of DNA and RNA exhibited positive result and lastly, for the test for inorganic phosphates, basic hydrolysate of DNA showed negative result. RNA is more susceptible to hydrolysis than DNA, especially in basic hydrolysis due to the presence of 2’ hydroxyl group.
