FIG. 5.
The effect of feedback mechanisms on the noise in gene expression. (a) Schematic of auto-activation model of gene expression. (b) Schematic of auto-repression model of gene expression. (c) The noise strength as a function of the positive feedback strength (a) for system (62), where the parameters are λ = γ = 1, μ = 5, δ = 0.1. (d) The noise strength as a function of the negative feedback strength (r) for system (71), where the parameters are λ = γ = 1, μ = 5, δ = 0.1.
