The latest article in Nature on gene codes finds that certain base pairs can be reversed by DNA in an 'excited state'creating an even broader code mechanism. Look at this abstract:- http://www.nature.com/nature/journal/vaop/ncurrent/full/nature09775.html-Hoogsteen base pairs expand the information available. In life it is information all the way down! And here, in a sense, the DNA can call up its own mutations when necessary. Fit this into Neo-Darwinism, if you can.
