검증된 단계별 안내1
Understand the structure of DNA: DNA is composed of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
Recognize the role of RNA: RNA, unlike DNA, contains uracil (U) instead of thymine.
Identify the bases listed in the problem: Thymine, Cytosine, Adenine, and Uracil.
Compare the bases with those found in DNA: Thymine, Cytosine, and Adenine are all found in DNA.
Conclude which base is not found in DNA: Uracil is the base that is not present in DNA, as it is found in RNA instead.
