Abstract
We examined here the problem of electronic conduction between two metallic leads via a DNA molecule. The formal analysis is accomplished through the use of T-matrix formalism of scattering theory and Löwdin's partitioning technique. We calculated conductance, DOS and I-V characteristics for a T.B model in the limit of small applied voltages. Considering Büttiker’s idea for inelastic scattering, we included environmental effects in our calculations and the results compared with the data in absence of environmental effects
