Genetical feedback repression. I. Single locus models

The process of genetical feedback-repression analogous to the Jacob-Monod system has been simulated by digital computer modelling, allowing inclusion of stochastic variation of the components. In the absence of stochastic variability, the model shows a damped oscillation over a wide range of specifications. Inclusion of stochastic variation results in the model maintaining oscillations which, if summed over several independent genetical feedback-repression loops, results in a regular oscillation.
