C
Thymine
D
Adenine
Verified step by step guidance1
Understand the structure of DNA: DNA is composed of two strands forming a double helix, with each strand consisting of a sequence of nucleotides.
Identify the four nucleotide bases in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recall the base pairing rules in DNA: Adenine pairs with Thymine, and Cytosine pairs with Guanine.
Focus on the base pairing involving Cytosine: According to the base pairing rules, Cytosine (C) pairs with Guanine (G).
Eliminate the incorrect options: Uracil is found in RNA, not DNA, and Adenine pairs with Thymine, not Cytosine.
