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 each base: Adenine pairs with Thymine, and Cytosine pairs with Guanine in the DNA double helix.
Identify the bases listed in the problem: Adenine, Thymine, and Cytosine are mentioned.
Recall the bases found in RNA: RNA contains Adenine, Uracil, Cytosine, and Guanine. Note that Uracil replaces Thymine in RNA.
Determine which base is not found in DNA: Since Uracil is present in RNA and not in DNA, it is the base not found within DNA.
