Text Solution

Verified by Experts

The correct Answer is:
A
Nitrogen bases are of two types-purines and Pyrimidines. Purities are 9 membered double ring nitrogen bases which possess nitrogen at 1, 3, 7 and 9 positions, e.g. adenine (A), guanine (G). Pyrimidines are 6-membered nitrogen bases that contain nitrogen at 1 and 3 positions, e.g. cytosine (C), thymine (T), uracil (U).
