Nitrogenous bases are categorized into two groups: pyrimidines (cytosine, thymine, and uracil) and purines (adenine and guanine).
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;
purines
DNA is composed of four nitrogenous bases, which are categorized into two types: purines and pyrimidines. The purines include adenine (A) and guanine (G), while the pyrimidines consist of cytosine (C) and thymine (T). These bases pair specifically (A with T and G with C) to form the rungs of the DNA double helix.
Four, out of whish 2 purines and two pyremidines
A DNA molecule consists of two strands that are made up of nucleotides. Each nucleotide is composed of a sugar molecule, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The two strands are connected by hydrogen bonds between complementary nitrogenous bases.
Purines and Pyrimidines
The two nitrogenous bases that are purines are adenine and guanine.
Adenine and Guanine are the two classes of nitrogenous bases that belong to purines.

The two chemical groups that form the backbone of a DNA strand are deoxyribose sugar and phosphate groups. These components link together to form a sugar-phosphate backbone, with nitrogenous bases attached to the deoxyribose sugar.
Nitrogenous bases form hydrogen bonds with one another. These hydrogen bonds are responsible for holding the two strands of DNA together in the double helix structure.
The category of nitrogen bases that consists of two rings is the purines.A nitrogenous base is an organic compound that owes its property as a base to the lone pair of electrons of a nitrogen atom. Notable nitrogenous bases include purines.Purines have two fused rings of carbon and nitrogen atoms.
