DNA Torsional Solitons in Presence of localized Inhomogeneities
arXiv:nlin/0112040 · doi:10.1238/Physica.Regular.066a00385
Abstract
In the present paper we investigate the influence of inhomogeneities in the dynamics and stability of DNA open states, modeled as propagating solitons in the spirit of a Generalized Yakushevish Model. It is a direct consecuence of our model that there exists a critical distance between the soliton's center of mass and the inhomogeneity at which the interaction between them can change the stability of the open state.Furtherly from this results was derived a renormalized potential funtion.
