The edges of each base pair are exposed in the major and minor grooves, creating a pattern of hydrogen-bond donors and acceptors and of hydrophobic groups (allowing for Vander Waals interactions) that identifies the base pair. The edge of an C : G base pair displays the following chemical groups in the following order in the major groove:

  1. A hydrogen-bond acceptor (at N7 of guanine), a hydrogen-bond acceptor (the carbonyl on C6 of guanine), a hydrogen-bond donor (the exocyclic amino group on C3 of cytosine), and a small nonpolar hydrogen (the hydrogen at C5 of cytosine)
