چکیده

We present a model to describe electrical conductivity along the DNA double helix. In this model, DNA is considered as a one-dimensional disordered system, and electrons are transported via variable range hopping between localized states. Thermal structural fluctuations in DNA further localize electronic wave functions, giving rise to a temperature-dependent localization length. The model quantitatively explains the temperature dependence of the conductivity observed in the lambda phage DNA (lambda-DNA).

Dipole relaxation losses in DNA

The electrodynamic response of DNA in the millimeter wave range is investigated. By performing measurements under a wide range of humidity conditions and comparing the response of single-stranded DNA and double-stranded DNA, we show that the appreciable ac conductivity of DNA is not due to photon-assisted hopping between localized states but is instead due to dissipation from dipole motion in t...

Charge transfer and charge transport on the double helix

We present a short review of various experiments that measure charge transfer and charge transport in DNA. Some general comments are made on the possible connection between various ‘chemistry-style’ charge transfer experiments that probe fluorescence quenching and remote oxidative damage and ‘phys-style’ measurements that measure transport properties as defined typically in the solid-state. We ...

Hitchhiking transport in quasi-one-dimensional systems

– In the conventional theory of hopping transport the positions of localized electronic states are assumed to be fixed, and thermal fluctuations of atoms enter the theory only through the notion of phonons. On the other hand, in 1D and 2D lattices, where fluctuations prevent formation of long-range order, the motion of atoms has the character of the large scale diffusion. In this case the pictu...

DFT approach to calculate electronic transfer through a segment of DNA double helix

The electronic structures of an entire segment of a DNA molecule were calculated in its single-strand and double-helix cases using the DFT method with an overlapping dimer approximation and negative factor counting method. The hopping conductivity of the segment was calculated by the random walk theory from the results of energy levels and wave functions obtained. The results of the single-stra...
