Correct answer: Thymine, Guanine
The nitrogenous base is the key to the proper functioning of the DNA. They allow complementary base pairing. The nitrogenous bases Adenine form two hydrogen bonds with thymine and the cytosine form three hydrogen bonds with the guanine.
Simply, A combines with T and G combines with the C. It is often called as a complementary base pairing because of each base pair bonds only with its specific complementary base partner in a DNA molecule.
