Whether the A-A base pair is complementary base pair in DNA molecules has to be stated. Concept introduction: In DNA double helix base pairs are bonded together by hydrogen bonds. In DNA, purine (adenine and guanine) base pairs bond with pyrimidines (cytosine and thymine).
Whether the A-A base pair is complementary base pair in DNA molecules has to be stated. Concept introduction: In DNA double helix base pairs are bonded together by hydrogen bonds. In DNA, purine (adenine and guanine) base pairs bond with pyrimidines (cytosine and thymine).
Solution Summary: The author explains that DNA double helix base pairs are bonded together by hydrogen bonds. In DNA molecules, A–T and G–C pairings are most favorable for hydrogen bonding.
