Metathesis reactions can occur between two inorganic salts (ionic compounds that are composed of cations and anions that produce a neutral net charge) when one of the. Cytosine deamination appears to be largely responsible for spontaneous mutations in the modern world because of its sensitivity to temperature (q 10 = 4), that reaction would have furnished a mechanism for rapid evolution on a warm earth as the temperature fell from 100° to 25 °c, the rate of.
