Regulation of chaos---the miracle of gene networks The gene networks are so complicated that they cannot be partitioned by branches. ‘Since a regulatory protein may act in combination with other signals to control many other genes, complex branching networks of interactions are possible.’ 1 In fact gene networks can be regulated by ‘generations’, or, time intervals. In the networks, the time intervals between states are determined by ‘the inevitable delays while signal molecule concentrations either accumulate or decline’ 2 . It’s just like a sufficient and necessary condition: only when the concentration get to a level can the state been activated; only when the concentration decline to a level can the reaction been stopped. Although how much complex is the network, there is still a simple logic being kept. In the paper by McAdams and Arkin, they examine the stochastic models for timing of signal protein production in prokaryotes, which is similar to the assignment this week: R+P<->RPc<->RPo which is similar to R+PR->RPo;
