How Do Charges Travel through DNA?-An Update on a Current Debate.

The effects of oligonucleotide sequence, base pairing, stacking, and duplex microstructure as well as donor-acceptor distance, labeling site, and driving force on charge-transfer reactions in DNA are of interest, yet relatively few experiments have been performed to address many of these issues. This article summarizes recent results on DNA-mediated charge transfer and highlights experimental and theoretical issues that are still unanswered or unresolved.
