| Popis: | A guanine radical cation (G(+•)) was site-selectively generated in double-stranded DNA and the hole transport from G(+•) to a GGG unit in G(+•)(TTG)(N)GG sites (N=1-4) was analyzed. The overall rate of the charge transfer exhibits a weak (algebraic) distance dependence, i. e. k ∝ N (η) with η = 1.7±0.2. This result supports that long-range hole migration in mixed DNA strands is a multistep hopping process between G bases. |
