Figure 5: Inferred transcription parameters are tightly constrained across gap genes.

(A,B) Inferred Pol II initiation rate $k_{\text{ini}}$ (A), and promoter mean occupancy $\langle n\rangle$ (B) for all genes across AP position.

(C,D) Inferred on-rate $k_{\text{on}}$ (C) and off-rate $k_{\text{off}}$ (D) as a function of mean occupancy $\langle n\rangle$ for all genes. Solid black lines represent the global trend using the mean value of ${\tau }_n$ (see formula in inset).

(E) Inferred switching correlation time ${\tau }_n$ as a function of mean occupancy $\langle n\rangle$ for all genes with a mean value of ${\overline{\tau }}_n=3.0\pm 1.2$ min (dashed line).

(F,G) Inferred burst size $b$ (F) and burst frequency $f$ (G) as a function of the mean occupancy $\langle n\rangle$. Solid black lines represent the global trend using the mean value of $k_{\text{ini}}$ and ${\tau }_n$ (see formula in inset).

Color code as in Figure 1C. Error bars are the 10 to 90^th percentiles of the posterior distribution. See also Figure S6.
