Answer / ritesh
purines and pyrimidines are nitrogen bases.
purines contains 6 membered pyrimidine ring fused to a 5
membered imidazole ring.
adenine and guanine are the major purines.
adenine is 6-amino derivative of parent purine,guanine is 2-
amino,6-oxypurine.
pyrimidines is a 6 membered hetero cyclic compound.
pyrimidines are uracil,thymine,cytosine.

Introduction (from Wikipedia) A purine is a heterocyclic
aromatic organic compound, consisting of a pyrimidine ring
fused to an imidazole ring. Pyrimidine is a heterocyclic
aromatic organic compound similar to benzene and pyridine,
containing two nitrogen atoms at positions 1 and 3 of the
six-member ring. It is isomeric with two other forms of diazine.
