Findings

Elementary excitations can be asymmetric based on polarization.

The model suggests potential influence on DNA molecular processes.

Torsional vibration spectrum characterized within the model.

Abstract

We calculate the spectrum of torsional vibrations of a double-stranded structure that models the double helix of the DNA. 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.
