Motivated by our view of chemical bonds as tunnel elements and by the studies of one-dimensional arrays of mesoscopic tunnel junctions, we investigate charge and dipole soliton dynamics in DNA molecules. We predict the existence of charge solitons in single-strand DNA and of charge and dipole solitons in double-strand DNA. We discuss possible roles of these excitations in DNA functioning, and propose specific experiments for testing our predictions.
