The four nitrogenous bases found in DNA are; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
There are four nitrogenous bases found in DNA that are called guanine, adenine, thymine and cytosine. They are abbreviated by the first letter in their name, or G, A, T and C.The bases can be divided into two categories: Thymine and cytosine are called pyrimidines, and adenine and guanine are called purines.he phosphate group and sugar are the same in every nucleotide, but there are four different nitrogenous bases: guanine, adenine, thymine and cytosine. They are often abbreviated by the first letter of each nitrogenous base: G, A, T and C.
