Phase 3 model (stochastic): limited supply. Focus on repression–derepression machinery causing changes between states with lsrGenes bound or unbound to LsrR. Top row: two single runs illustrating stochasticity of the repression–derepression machinery; Bottom row: average over 1000 runs of repression–derepression machinery showing initial repressed state will be reached again as AI2_P approaches zero steady state
