Adenine
|
|
|
Cytosine
|
|
|
Guanine
|
|
|
Thymine

Explanation:
Detailed explanation-1: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
Detailed explanation-2: -This is known as a complementary base pairing. The purines form hydrogen bonds with pyrimidines, in which adenine bonds only to thymine in two hydrogen bonds, and cytosine bonds only to the guanine in three hydrogen bonds.
