Question

Quizplus · Accepted Answer

Thymine and Adenine are a complementary base pair that forms 2 hydrogen bonds. This is a well-established fact in biology and is a key component of the double helix structure of DNA. Cytosine and Guanine also form a complementary base pair, but they form 3 hydrogen bonds instead of 2. Thymine and Guanine do not form a complementary base pair, as their chemical structures do not allow for hydrogen bonding.
