Arsenic in DNA: The Kinetic Argument.
Here's the first response in the chemical literature to the arsenic-in-DNA controversy, from three authors in ACS Chemical Biology. They detail the argument, familiar to readers of the comment section here, that arsenate esters just would not be expected to have the hydrolytic stability needed for arseno-DNA to function usefully.
How far off is it? By, well, about
13 (make that 17) orders of magnitude, which is much worse than I'd thought. As the authors put it, "Overcoming such dramatic kinetic instability in its genetic material would present serious challenges to Halomonadacea GFAJ-1." Indeed it would.
