Which of the following is NOT one of the four bases found in DNA?

Explanation:
DNA uses four bases—adenine, thymine, cytosine, and guanine. Uracil is not among them; it is used in RNA in place of thymine. In RNA, adenine pairs with uracil, while in DNA adenine pairs with thymine. So Uracil is the base that is not found in DNA.
