Autocatalytic simulations of chemical dormancy. (A) The ratio of active molecules ($A_a$) to inactive molecules ($A_i$) increases with catalyst ($B$) abundance in a simple autocatalytic simulation. (B) The total abundance of molecule $A$ exponentially decreases with the rate that inactive molecules decay consistent with the view that protection afforded by dormancy can contribute to the persistence of molecules over time. Dormant molecules decay at each time step with probability d.
