Figure 2

Two views of a dinucleotide platform submotif (here 5′-GpU-3′). The blue slabs depict the planes of the adjacent nucleobases. The approximate coplanarity of the bases is a distinctive feature of all dinucleotide platforms. The green solid lines denote the interbase side-by-side pairing and the green dashed lines symbolize the O2′…O2P H-bond typical of GpU33.
