We come to the conclusion that within the framework of the model elementary excitations may display an asymmetry as regards their winding and direction of the propagation, depending on initial polarization. The asymmetry could have a bearing on processes that take place in molecules of the DNA.7 pages, Latex, 2 figuresSoft Condensed MatterQuantitative Biologytext
