Which nitrogenous base is part of DNA but not RNA?

Explanation:
Distinction between DNA and RNA bases. DNA uses thymine, while RNA uses uracil instead of thymine. Thymine is found in DNA but not in RNA, which instead has uracil. This difference is what differentiates the two nucleic acids, so thymine is the base that is present in DNA but not in RNA.
