Abstract
Numerous studies of the long-distance hole-migration process through a DNA double strand have revealed detailed insight into the distance and sequence dependence of charge-movement processes.[1-4] In contrast to the wealth of information nowavailable on the long-distance hole transfer,[5-9] less is known about the complementary excess-electron-transfer process in which an anion, instead of a cation, moves through the duplex.We,[10-13] and others,[14-19] have recently shown that excess electrons move through DNA by a hopping-type mechanism in which the pyrimidine bases dT and dC act as ,stepping stones-File in questo prodotto:
