The numerical experiments which demonstrate the possibility of polaron charge transfer in a homogeneous finite unclosed G/C DNA chain due to the interaction with localized excitations have been carried out in the absence of an electric field. As a model, which describes the dynamics of a DNA molecule, was considered the Peyrard-Bishop-Holstein model. It is shown that, depending on the parameters of the selected initial excitations and on the parameters of the chain, the polaron can move over long distances (about a thousand sites). It is also shown that the ability of a polaron to move and the character of this movement significantly depend on the relative positions of the polaron and the selected localized excitations.
