Bifurcation Analysis for Phage Lambda with Binding Energy Uncertainty
Figure 1
Three binding sites on a DNA segment. The sites , , and can be bound by CI dimer, Cro dimer, or RNA polymerase. This DNA segment consists of promoters and . If the RNA polymerase binds to , cI gene is expressed; if the RNA polymerase binds to and , cro gene is expressed. The amount of Cro and CI in the cell directly determines which state phage is in.
