As a two-gene network with stable solutions, our system does not always show sustained oscillations. However, factors such as different transcription rates from the two promoters, coupled with tight regulation (non-leakiness) of the promoters, can result in a situation in which oscillations are maintained.

One cell may be designated to represent many cells by allowing it to excrete and absorb many times the single-cell values of autoinducer:
