An example of gene product concentration variations. Gene product concentration variations for the TEM shown in Fig. 7. The behavior corresponds to the qualitative cycle (+, -) → (+, +) → (-, +) → (-, -) → (+, -). The dashed curves represent the clock and concentration evolution of Y. The other curves represent the clock and concentration evolution of X. The delay intervals stand for a minimal and a maximal time between two resets of the corresponding clock.
