Recall that DNA is composed of four nitrogenous bases, which are divided into two categories: purines and pyrimidines.
Identify the purines in DNA: Adenine (A) and Guanine (G).
Identify the pyrimidines in DNA: Cytosine (C) and Thymine (T).
Remember that Uracil (U) is found in RNA, not DNA, so any list containing Uracil is incorrect for DNA bases.
Therefore, the correct list of nitrogenous bases in DNA is Adenine, Thymine, Cytosine, and Guanine.
