Figure 1: The plots of the dynamics of protein concentrations A and R for different values of system size, V=1, 20, 50, 100 and 1000 respectively. The parameter values are taken from Vilar et al. [3] for fixed point oscillation. Panels (a), (b), (c), (d), (e) and (f) show the variations of concentrations of A and R as a function of time in hours for various values of V. Panels (g), (h), (i), (j), (k) and (l) are two dimensional plots of A as a function of R for corresponding values of V.
