This is a plain CPK model, but with a world map texture-mapped onto the surface.It was riginally a demo for one of my commercial clients. They decided they wanted something a little different, so I put it up here
This model has the same atomic positions and balls colored by element,but now the sticks convey other information: the backbones are red and blue, and the bases are purple (Adenine), en (Thymine), yellow(Guanine), and cyan (Cytosine).
