  • Title: [Dynamics of kinks in inhomogeneous polynucleotide chains].
    Author: Iakushevich LV, Riasik AA.
    Journal: Biofizika; 2013; 58(4):565-72. PubMed ID: 24455876.
    Abstract:
    In the present paper the dynamics of the nonlinear conformational excitations--kinks, in inhomogeneous polynucleotide DNA chains is investigated. To calculate the kink rest energy E0 and its length d the method of dynamical interval is used. This makes it possible to take into account that all coefficients of the model dynamic equation--the sine-Gordon equation depend on the sequence of bases. It is shown that the method gives an opportunity to calculate dynamical characteristics of any artificial and real sequences that is important for implementing tasks associated with the search and analysis of functionally important DNA sites.
