Voet Fig. 3-6
Note that the strands run antiparallel
Note that the helix is 20 Å wide.
There are about 10 base pairs per turn of the helix.
One turn of the helix is 34 Å
The base pairs are 3.4 Å apart

Backbones of the strands are bright green and bright red
The bases on the corresponding backbones are lighter green and pink
