Hasse diagram of organizations for Model 2 in different modifications. Left: Organizational diagram of unmodified Model 2 (including attachment reaction KinU → KinA). The only interesting organization is highlighted in green. Right: Organizational diagram of modified Model 2 (no attachment reaction KinU → KinA). Only new species are shown for overviews sake. Again there exist three interesting organizations, which are highlighted. Oinit = {Activator, Inhibitor, Promotor, Promotor_A, Promotor_I, KinU} corresponds to the initial present species (no attached kinetochores). Otrans = {Activator, Inhibitor, Promotor, Promotor_A, Promotor_I, KinU, KinA} corresponds to the transitional phase (both, attached and unattached kinetochores are present). Ogo = {Activator, Promotor, Promotor_A, KinA} same organization as on the left side (only attached kinetochores).
