Coupled positive and negative feedback loops are often found in biological systems that support oscillations. Here we consider genetic regulatory circuits. Two species of proteins A and B interact by activation/repression of their respective expression: A activates the production of itself as well as that of B, which in turn represses A. Starting from a previous deterministic study of that model we chose a fully stochastic approach to learn about the effect of the inherent noise in such (typically small) systems.
