This tutorial takes the reader step by step on how to create a mathematical model of the first synthetically constructed genetic toggle switch, in order to investigate the dynamic behaviour of the circuit. A system of nonlinear ordinary differential equations based mass action kinetics is set ups the system is solved analytically, for a simplified system; then the nonlinear system is solved numerically using MATLAB; the results of the two approaches are compared; stability of the system is explored, to figure out how the output of the toggle switch is affected by various parameters and input combinations.
