Popis: We study nonlinear dynamics of the DNA molecule relying on a helicoidal Peyrard–Bishop model. We look for traveling wave solutions and show that a continuum approximation brings about kink solitons moving along the chain. This statement is supported by the numerical solution of a relevant dynamical equation of motion. Finally, we argue that an existence of both kinks and localized modulated solitons (breathers) could be a useful tool to describe DNA–RNA transcription.We study nonlinear dynamics of the DNA molecule relying on a helicoidal Peyrard–Bishop model.
