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 linear. We can choose to see the base pairs, which show very neatly. First, the G-C pairs: are in blue and dC-G are in yellow. Similarly, we can see the dA-U in red and the dT-A in purple (note that the RNA has U nucleotides instead of T). Furthermore, we can also see the purine and pyrimidine for a more general view of the bases. Because this is the B form of DNA:RNA interaction, all hydrogen bonds between the bases are through the Watson Crick faces. If we choose to see the ions, as we'd expect, the whole complex shines.
