On the Long-Range Charge Transfer in DNA

摘要: The sequence dependence of charge transport through stacked Watson−Crick base pairs was analyzed for coherent hole motion interrupted by a temporary localization on guanine bases. relative rate transfer to the GGG has been expressed in terms frequency jumps adenine−thymine separating adjacent sites. obtained expression yields practically same as measurements, without invoking adjustable parameters. For alternating adenine−thymine/guanine−cytosine sequences, our analysis predicts that charge-transfer varies inverse proportion length at short distances, with change slow exponential decay longer distances.
