The life story of hydrogen peroxide II: a periodic pH and thermochemical drive for the RNA world

Ball, Rowena; Brindley, John


It is now accepted that primordial non-cellular RNA communities must have been subject to a periodic drive in order to replicate and prosper. We have pro- posed the oxidation of thiosulfate by hydrogen peroxide as this drive. This reaction system behaves as (i) a thermochemical and (ii) a pH oscillator, and in this work, we unify (i) and (ii) for the first time. We report thermally self- consistent, dynamical simulations in which the system transitions smoothly from nearly isothermal pH to...[Show more]
