    DNA and RNA charge transport effect of sequence, stacking, structure and Hg incorporation

  • Original language description

    In this work experimental and theoretical approaches have been combined for unique study and comparison of charge transfer efficiency in standard and modified (Hg incorporated) DNA duplexes and DNA/RNA hybrids. Specific mechanism proposed to account forthe on-chain oligonucleotide charge transport is based on polaron formation-charge is transported coherently by long-distance tunneling (superexchange). A key parameter in this approach is how the bridge orbitals of the intervening DNA bases couple the charge donor and acceptor - this is strongly controlled by specific oligomeres structures and conformation. The RNA/DNA system flexibility also improves the conditions for polaron creation and thus may facilitate rapid (coherent) charge transport in the DNA/RNA hybrids.
