Before revision: We make rigorous the notion of universality in well-mixed stochastic models of biochemical feedback , namely that they scale near their bifurcation point according to the exponents of the mean-field Ising universality class. In doing so, we derive a mapping of the biochemical parameters to an effective temperature, magnetic field, order parameter, and heat capacity .
After revision: We make rigorous the notion of universality in well-mixed stochastic models of biochemical feedback , namely that they scale near their bifurcation point according to the exponents of the mean-field Ising model near the critical point. The mapping provides an effective temperature, magnetic field, order parameter, and heat capacity .
