The four nitrogenous bases found in DNA are; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
There are five different nitrogen bases that work to create the nucleotides found in DNA and RNA. They fall into two categories, listed below: 1. Pyrimidines: Bases that contain only 1 ring. Included in this group are: Cytosine, Thymine (DNA only), and uracil (RNA only) 2. Purines: Bases that contain 2 rings.
