Self-organization and nonlinear dynamics of nucleic acid-water system

We proceed our research on the physical modeling of the conformational tran sitions in the nucleic acid molecule during the water desorption-resorption cycle. The nucleic acid-water system is considered as an open system and s imulated with a trigger model. The analysis of kinetic equations and the an alysis based on the nonlinear master equations show the nontrivial bifurcat ion behavior of the system which leads to the multistability. This fact all ows one to explain the hysteresis phenomena observed experimentally in the nucleic acid-water system by the presence of the metastable states. Besides , autowave processes, such as traveling fronts of a new conformation (trigg er waves), oscillations are possible in the corresponding distributed param eter system, if the diffusion of the water molecules is taken into account. The problem of self-organization in the nucleic acid-water system is of gr eat importance for revealing physical mechanisms of the functioning of nucl eic acids and for many specific practical fields.
