The abstract maybe a tad general, but the paper specifically refers to the movement of a single proton : " As initially proposed by Delbruck et al. (1935) and Schrodinger (1944) and Watson and Crick (1953), spontaneous mutations are initiated by quantum jump events such as tautomeric shifts in single protons of DNA bases." You reference catalysts and there are some indications this is a quantum tunneling phenomena : Here is a talk by Professor Nigel Scrutton of the University of Manchester who has many papers on this, Quantum effects in biological catalysis https://www.youtube.com/watch?v=SnxmHlbtJDI https://www.youtube.com/watch?v=SnxmHlbtJDI ---- Here is Donald's paper criticising McFadden and al-Khalili's ideas http://people.bss.phy.cam.ac.uk/~mjd1014/qevrev.pdf http://people.bss.phy.cam.ac.uk/~mjd1014/qevrev.pdf and their rebuttal : http://arxiv.org/abs/quant-ph/0110083v1 http://arxiv.org/abs/quant-ph/0110083v1 --- The 2012 Quantum Biology Conference at the IAS has some excellent papers - which are (too briefly) summarised into the OP article. http://www.ias.surrey.ac.uk/workshops/quantumbiology/ http://www.ias.surrey.ac.uk/workshops/quantumbiology/
