Comparison of the numerical and approximate analytical solutions of the non-linear protein translation model. Examples of the exact numerical (circles) and approximate analytical (solid lines) solutions of the non-linear protein translation model. a) For the set of parameters k1 = 2, k2 = 2, k3 = 5, k4 = 0.1; b) For parameters k1 = 1, k2 = 5, k3 = 50, k4 = 0.01; c) For the set of parameters from , k1 = 2, k2 = 2, k3 = 5, k4 = 1; d) Reaction fluxes for the set of parameters c). Dashed black vertical lines denote evaluated transition points between the dynamics stages. Dashed red vertical points denote the time points where [40S](t) = 10·[eIF 4F](t) and [40S](t) = [eIF 4F](t)/10 respectively.
