- Example: H R 11' COO- Ca ↓ NH3 L or D?43. In DNA the nucleic acid bases form hydrogen bonds between them, which are responsible for the formation of the double-stranded helix. A hydrogen bond donor is defined as any hydrogen atom that can participate in a hydrogen bond, whereas a hydrogen bond acceptor is defined as any atom that can "receive" that hydrogen atom to form a hydrogen bond. How many hydrogen bond acceptors does guanine (shown below) have?
