검증된 단계별 안내1
Understand the context: DNA is composed of four main nitrogenous bases that pair with each other to form the rungs of the DNA double helix.
Identify the four nitrogenous bases found in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recognize that Uracil (U) is a nitrogenous base found in RNA, not DNA. In RNA, Uracil replaces Thymine.
Compare the given options with the known DNA bases: Thymine, Adenine, and Cytosine are all found in DNA.
Conclude that Uracil is the base not found in DNA, as it is specific to RNA.
