Sequence correlations affect charge transfer efficiency.

Backscattering profiles can be inferred from sequence correlations.

Aperiodic DNA sequences exhibit distinct charge transfer properties.

Abstract

We address the relation between long range correlations and charge transfer efficiency in aperiodic artificial or genomic DNA sequences. Coherent charge transfer through the HOMO states of the guanine nucleotide is studied using the transmission approach, and focus is made on how the sequence-dependent backscattering profile can be inferred from correlations between base pairs.
