The peculiarities of polaron motion in the molecular polynucleotide chains of finite length

The numerical experiments which demonstrate the possibility of polaron charge transfer in a homogeneous finite unclosed G/C DNA chain in the absence of an electric field and additional excitations have been carried out. As a model, which describes the dynamics of a DNA molecule, was considered the Peyrard–Bishop–Holstein model. It is shown that the polaron placed at the initial moment of time not in the center of the chain, acquires the ability to move. It is also shown that the velocity of the polaron movement in the chain depends on its initial form.
