Figure 4

(A) By increasing protein production from low to high, a transition can occur from Level 1 to Level 2. Note degradation is low in both Level 1 and Level 2. (B) Level 1 can also be achieved with high production and high degradation. In this case, lowering degradation enables a faster transition from Level 1 to Level 2. (C) Protein pulses with high (blue) and low (brown) frequencies. High-frequency protein pulses (blue) show short pulse duration while low-frequency protein pulses (brown) show longer pulse duration. (D) Protein pulses with high (blue) and low (brown) amplitudes.
