Global force-torque phase diagram for the DNA double helix: structural transitions, triple points and collapsed plectonemes

We present a free energy model for structural transitions of the DNA double helix driven by tensile and torsional stress. Our model is coarse grained, and is based on semiflexible polymer descriptions of B-DNA, underwound L-DNA, and highly overwound P-DNA. The statistical-mechanical model of plecton...
