Packing and twisting of rope-like structures

We show that DNA optimizes a local volume fraction and explain its counterintuitive behavior under strain, i.e. that it rotates opposite of unwinding. Other examples which will be discussed include the alpha-helix, collagen, the nucleosome, and good old rope.
