Which set lists the nucleobases?

• A. Adenine, Guanine, Cytosine, Thymine
• B. Thymine, Adenine, Cytosine, Guanine
• C. Cytosine, Guanine, Thymine, Adenine
• D. Cytosine, Guanine, Adenine, Thymine

Answer: (C)

Recognizing the four DNA nucleobases. DNA is built from adenine, thymine, cytosine, and guanine. A listing that includes all four—regardless of order—shows the nucleobases correctly. Cytosine, Guanine, Thymine, Adenine contains exactly those four bases, just arranged differently. Since the goal is to name the bases present, any order that lists A, T, C, and G is correct, and the other listings do the same. The key idea is that the four nucleobases are A, T, C, and G.
