Question

A nucleic acid whether DNA or RNA on complete hydrolysis, two purine bases, two pyrimidine bases, a pentose sugar and phosphoric acid.Nucleotides which are intermediate products in the hydrolysis contain

• A. Purine or pyrimidine base and ortho phosphoric acid
• B. Purine or pyrimidine base and pentose sugar
• C. Purine or pyrimidine base, a pentose sugar and ortho phosphoric acid
• D. a purine base, a pentose sugar and ortho phosphoric acid

Answer 1

Answer: (C)

Purine or pyrimidine base, a pentose sugar and ortho phosphoric acid

Answer 2

Nucleotides are the building blocks of nucleic acids (DNA and RNA) and consist of three main components: a nitrogenous base (either a purine or pyrimidine base), a pentose sugar (ribose in RNA or deoxyribose in DNA), and a phosphate group (orthophosphoric acid). When nucleic acids undergo complete hydrolysis, these components are released as individual nucleotides.
Therefore, the correct answer is (C) a purine or pyrimidine base, a pentose sugar, and ortho phosphoric acid.
