Interpretation:
The reason for the acidity of
Concept introduction:
The nucleic acids (DNA and RNA) consist of a sugar, phosphate and nitrogenous bases.

Answer to Problem 24SSC
The phosphate ion of the nucleic acid is almost comparable to phosphoric acid and is the reason for the acidity of the nucleic acid.
Explanation of Solution
The phosphate attached to the sugar has two bonded protons with the sugar of the nucleic acid leaving only one free proton which is highly acidic.
The part of nucleic acid that makes it acidic is the phosphate.
