1. Although this type of base pairing is incompatible with the structure of the canonical

2. the purine base is rotated relative to that in the standard base pair, reduces the distance between the C1 carbon atoms of the associated sugar moieties

   • DNA double helix, it is found in other structural forms of DNA, notably H-DNA and Gquadruplexes
