Abstract
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)NGG 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.
