Figure 3.
(A) Stereo view looking into the major groove of mopholino-9-amino-DACA intercalated into the d(CpG).d(GpC) site of the d(CpGpT).d(GpCpA). Dashed lines indicate possible hydrogen bonds. (B) Stereo view of the projection down the helix axis of a d(CpG).d(GpC) dinucleotide with sandwiched intercalated ligand (bonds drawn in black).
