Long-Range Hole Transport in DNA
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 µ Nh with h = 1.7±0.2. This result supports that long-range hole migration in mixed DNA strands is a multistep hopping process between G bases.
