Question:
Hydrolysis of nucleic acid gives nitrogenous base, sugar and ...............
Hydrolysis of nucleic acid gives nitrogenous base, sugar and ...............
Show Hint
Nucleic acid hydrolysis releases nitrogenous bases, sugars, and phosphoric acid due to cleavage of phosphodiester linkages.
Updated On: Jun 26, 2026
- Sulphuric acid
- Phosphorous acid
- Sulphurous acid
- Phosphoric acid
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Recall nucleic acid composition.
Nucleic acids (DNA and RNA) are composed of nitrogenous bases, pentose sugar, and phosphate groups.
Step 2: Hydrolysis reaction.
Upon hydrolysis, the phosphodiester bonds are broken, releasing phosphate ions along with nucleotides (base + sugar).
Step 3: Identify the acid formed.
The phosphate groups in nucleic acids give phosphoric acid (H\(_3\)PO\(_4\)) upon hydrolysis.
Step 4: Conclusion.
\[ \boxed{\text{Phosphoric acid is the product released along with nitrogenous base and sugar.}} \]
