Fig. 4: The length of external OFF periods is controlled by both the Pho4 activator and chromatin remodelers.

a Survival curves of external OFF periods for wild type, b chd1\(\Delta\), c isw2\(\Delta\), and d pho4. Measurements were fit by a single exponential, i.e., \(P(T > t)={e}^{-\lambda t}\) (blue curves). The corresponding densities, \(f(t)=\lambda {e}^{-\lambda t}\) (not shown), are strictly monotone (non-peaked). The median of the distribution is highlighted by stippled red lines; \(\mu\) is the mean period length (the average of 300 bootstrap replicates).
