Circular closed DNA. Topology, energy, and stress at different equilibrium configurations and deformation conditions

The topology of circular closed DNA in different equilibrium configurations and deformation conditions has been investigated. The distribution of twisting and bending energy and stress has been assessed. It is shown that the twisting/bending stiffness ratio qualitatively influences the deformation o...

Zusammenfassung:	The topology of circular closed DNA in different equilibrium configurations and deformation conditions has been investigated. The distribution of twisting and bending energy and stress has been assessed. It is shown that the twisting/bending stiffness ratio qualitatively influences the deformation of a circular DNA molecule.
