Question

what is the complementary base pairing order in dna? (1 point)
adenine - cytosine, thymine - guanine
adenine - thymine, cytosine - guanine
adenine - thymine, cytosine - uracil
adenine - cytosine, uracil - guanine

Explanation:

In DNA, complementary base pairing occurs. Adenine (A) pairs with Thymine (T) through two hydrogen bonds. Cytosine (C) pairs with Guanine (G) through three hydrogen bonds. Uracil (U) is found in RNA, not DNA.

Answer:

Adenine - Thymine, Cytosine - Guanine
