The shown representation is a DNA:RAN hybrid duplex. This is the in orange and this is the in green. Notice that all hydrogen bonds between the bases are . We can choose to see the base pairs, which show very neatly. First, the G-C pairs: are in blue and are in yellow. Similarly, we can see the in red and the in purple (note that the RNA has U nucleotides instead of T). Furthermore, we can also see the bonding with each other (never with themselves) for a more general view of the bases. In this generic RNA:DNA hybrid all hydrogen bonds between the bases are through the , as shown for the dG-C pair. If we choose to see the in the hybrid, as we'd expect, the whole complex shines: the backbone and the nucleotides are negatively charged.
