Theory of electric conductance of DNA molecule
Article Abstract:
The electric conductance of DNA molecules was studied theoretically using the tight binding small polaron model. The distinct temperature dependences of the coefficient observed in the two DNA molecules would indicate that, although the poly(dG)-poly(dC) molecule is in the incoherent regime, the poly(dA)-poly(dT) is in the quasicoherent regime.

Theoretical rate constants of super-exchange hole transfer and thermally induced hopping in DNA
Article Abstract:
The reorganization energies, the activation energies, the electronic coupling matrix elements, and the rate constants of hole transfer in B-form double-helix DNA in water is studied theoretically. The classical molecular mechanics (MM) method is used to determine the nuclear Franck-Condon factor of a system involving both DNA and solvent.

Torsional deformation of double helix in interaction and aggregation of DNA
Article Abstract:
Sequence dependent twisting between adjacent base pairs and torsional elasticity of double helix into the theory of DNA interaction is discussed. An increase in the expected counterion concentration required for aggregation of nonhomologous DNA and slightly higher solubility of such DNA above the critical concentration.
