Recent developments of charge injection and charge transfer in DNA.

The question of whether and how electrons migrate through DNA was a matter of controversial discussion over the last ten years. Today, there is no doubt that long distance charge migration through DNA exists and most scientists explain this process by a multistep hopping mechanism. This feature article presents recent developments of our group on the injection of a positive charge into DNA bases and the transfer of the charge between the DNA bases. The influence of the donor, the nature of the bridge, and the distance between the donor and the acceptor are discussed.
