Figure 6

Comparison of the tag and mRNA frequency marginal modes ($\tilde{\theta }$ and $\tilde{m}$ respectively) during log growth phase. Data is presented on a log-log scale with a 1:1 line for reference. Genes whose tag formation cutting probability φ _i is greater that the mean tag formation probability $\overline{\Phi }$ are over represented in the tag pool and, consequently, occur below the 1:1 line. Conversely, genes whose tag formation cutting probability φ _i is less that $\overline{\Phi }$ are under represented in the tag pool and occur above the 1:1 line.
