Cytosine (C)

D
Adenine (A)
검증된 단계별 안내1
Recall the base pairing rules in the DNA double helix structure, which are based on complementary hydrogen bonding between nucleotides.
Identify the four nucleotides in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Remember that Adenine (A) pairs specifically with Thymine (T) through two hydrogen bonds, forming a stable base pair.
Note that Cytosine (C) pairs with Guanine (G), and Uracil (U) is found only in RNA, not DNA.
Conclude that thymine (T) always pairs with adenine (A) in the DNA structure.
