What if DNA lived on lattices?

The understanding of configurational changes of nucleic acids is a challenging problem is biochemistry. Since the discovery of the double helical structure of DNA, various simplified models for its dynamics and configurations have been proposed. In some of these models, the DNA bases are sitting on lattice points and are free to move on the lattice according to local moves. In order to understand the effect of the local moves we use cubical complexes whose appearance and geometry depends on what the local moves are. In this talk, I will give examples of such complexes and describe what we would like to be visualized.
