Figure 7.

Computed average number of kinks (open base pairs) per molecule in circular DNA as a function of the number of bp in DNA. The bending potential at the disruptions correspond to Equation (3) with b = 0.3 and h = 16, which corresponds to the free energy of the disruption formation close to 7 kcal/mol, found experimentally (see the text). Changes in DNA torsional stress related to the disruption formation were not taken into account in the calculations that were performed as described in (1).
