WebThe bond joining the 1'-carbon of the deoxyribose sugar to the heterocyclic base is the N -glycosidic bond. Rotation about this bond gives rise to syn and anti conformations ( Figure 5 ). Rotation about this bond is restricted and the anti conformation is generally favoured, partly on steric grounds. Figure 5 WebWhile the phosphodiester bond is absent in the NTP duplex stacks, the triphosphate group, having a molecular volume (∼400 Å 3 per base) that cannot be accommodated in any simple vertical stacking, drives, along with the ribose, the tendency for adjacent base pairs to a nonzero relative azimuthal orientation about the helix axis, z (Fig. 1G).
