In the version of this Article originally published, in ref. 19, in the author list, the second, third and fourth authors were not included and the reference should have read: 'Grib, N. V., Ryndyk, D. A., Gutiérrez, R. & Cuniberti, G. Distance-dependent coherent charge transport in DNA: crossover from tunneling to free propagation. J. Biophys. Chem. 1, 77–85 (2010).' This has now been corrected in the online versions of this Article.
