Question

Quizplus · Accepted Answer

Hydrogen bonds are responsible for the pairing between A and T (or G and C) nucleotides in DNA. Hydrogen bonds are weaker than covalent or ionic bonds, but they are still strong enough to hold the two strands of DNA together in a double helix structure. Hydrophobic bonds do not play a role in the chemical affinity between nucleotides in DNA.
