The four nitrogenous bases found in DNA are; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
DNA is made up of a phosphate group, a deoxyribose (sugar), and a nitrogen base. The nitrogen base can be broken down into 4 types(nucleotides): adenine, guanine, thymine, orâ¦ cytosine; and categorized into purines: adenine and guanine; and pyrimidines: cytosine or thymine. *Thymine is replaced by uracil in RNA.
