Comparison of I – V dependences in poly(dA)-poly(dT) DNA molecules extracted from figure 2(a) in [11] (symbols) with theoretical W (E,T) against E dependences (solid curves) calculated for the same T as in the experiment (from top to bottom) using the following parameters: ε_T = 0.21 eV,m* = 1.5 m_e, ħω = 43 meV and S = 12.
