Answer #1

Adenine forms 2 hydrogen bonds with Thymine.

Guanine forms 3 hydrogen bonds with Cytosine.

It is called complementary base pairing because each base can only bond with the corresponding base partner. The structures complement each other like a lock and a key.

C will only bond with G and A will only bond with T in DNA. So, Thymine and Guanine cannot complement each other.

This arrangement is worse than the complementation of thymine with adenine and guanine with cytosine because A-T and G-C are complementary base pairs.
