We present a novel electromagnetic model of DNA molecules, in which the P-bonds act as tunnel junctions and the H-bonds as capacitors. Excess charge in the model gives rise to two coupled modified sine-Gordon equations, which admit topological solitonic excitations. We study the dynamics of the solitons, their effect on the DNA transport properties, and comment about their role in the DNA functioning. We propose specific experiments in order to test our predictions.
