Adenine, guanine, cytosine and thymine
(also in RNA, there is uracil instead of thymine)
DNA contains four nitrogen-containing bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases pair up in specific combinations: A with T and C with G.
Hydrogen bonds hold nitrogen-containing bases together in DNA. These bonds form between adenine and thymine (A-T) and between cytosine and guanine (C-G) in a DNA double helix.
Molecules that contain nitrogen in addition to carbon, oxygen, and hydrogen include amino acids, nucleic acids (DNA and RNA), and various nitrogen-containing bases and neurotransmitters.
One example of a biological compound that contains both oxygen and nitrogen is DNA (deoxyribonucleic acid). DNA is composed of nucleotides, which are made up of a nitrogenous base (containing nitrogen) attached to a sugar molecule and a phosphate group (containing oxygen). These nitrogenous bases are adenine, guanine, cytosine, and thymine.
Compounds containing nitrogen and oxygen are called nitrogen oxides. These compounds can have various chemical properties and can be produced through the combustion of fossil fuels or industrial processes.

Nitrogen containing bases
These bases are called pyrimidines.
The large bases that have two carbon-nitrogen rings are called purines.
DNA contains four nitrogen-containing bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases pair up in specific combinations: A with T and C with G.
The rungs of DNA are made up of the nitrogenous bases Adenine (A), Cytosine (C), Guanine (G) and Thymine (T). Each rung represents the bonding of two bases (one from each DNA strand). A binds with T and C binds with G.
Three nitrogenous bases make up a single codon.
AUG Start codon containing three nitrogenous bases.

These rings are known as pyrimidines.
