Which nitrogen base dose DNA contain?
DNA contains two types of nitrogen bases. There are the purines, which include Adenine and Guanine, and the pyrimidines, which include Thymine and Cytosine.
Adenine ALWAYS bonds with Thymine, and Guanine ALWAYS bonds with Cytosine, unless, of course, we have a mutation.
