  • Title: Asymmetric elastic rod model for DNA.
    Author: Eslami-Mossallam B, Ejtehadi MR.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2009 Jul; 80(1 Pt 1):011919. PubMed ID: 19658741.
    Abstract:
    In this paper we consider the anharmonic corrections to the anisotropic elastic rod model for DNA. Our model accounts for the difference between the bending energies of positive and negative rolls, which comes from the asymmetric structure of the DNA molecule. We will show that the model can explain the high flexibility of DNA at small length scales, as well as kink formation at high deformation limit.
