Generalized Dynamics of the Conformational Mobility in the DNA Molecule
V.B. Nemtsov and A.N. Kamluk

The proposed dynamic model of conformational mobility in DNA macromolecules is a generalization of the models used to study conformational vibrations and conformational transition dynamics, as a longitudinal component in this model is taken additionally into account. For quantitative estimation of the obtained results (for the calculation of a force constant) we used the DNA macromolecule elastic model in the form of two twisted springs inserted into each other. As a result the analysis, the dispersion curves for the generalized model of DNA macromolecules have been obtained. Thus, the offered model of the double-stranded DNA conformational mobility describes an experiment and can be used for non-contradictory interpretation of the experimental data and description of the DNA conformational dynamics in low-frequency range.
Key words: conformational vibrations, force constants, dispersion curves
