Figure 1

Transcriptional genetic circuits from the literature. Figure illustrating the circuit architectures associated to Table 1. In the graphical representation, we have made the distinction between non-competition and competition models by solid and dashed arrowed lines, respectively. In the notation n₁, n₂, ... characterizing the interactions in the schematic figures, the comma separates various binding sites and the degree of the multimer binding to that site. The notation n₁ + n₂ is employed only for subfigure (c) - see discussion in the Table 1.
