(a)
Interpretation:
The four major heterocyclic bases in DNA has to be given.
Concept Introduction:
Composition of
Nitrogenous bases: Five types of nitrogenous bases (has unique one-letter code A, G, T, U, and C) are derived from two parent compounds called purine and pyrimidine. The purine derivatives are Adenine and Guanine are two fused nitrogen containing rings. The pyrimidine derivatives are Thymine, Cytosine, and Uracil are nitrogen containing six-membered ring. Adenine, Guanine, Thymine, and Cytosine are the nitrogenous bases present in DNA. Adenine, Guanine, Cytosine and Uracil are the nitrogenous bases present in RNA.
(b)
Interpretation:
The four major heterocyclic bases in RNA has to be given.
Concept Introduction:
Composition of nucleic acid: Nucleic acid is a polymer of nucleotides. Each nucleotide has three parts: a sugar, a nitrogenous base, and a phosphate group.

(c)
Interpretation:
In both RNA and DNA, difference in heterocyclic bases has to be given.

Numbering the atoms in sugar and base rings:
In order to distinguish the atoms in the sugar of a nucleoside and atoms of a base ring, numbers without prime is used for atoms in the base ring and numbers with prime used for the atoms in the sugar ring.
