Intrinsic promoter strength explains differences between promoter classes. (A) The effect of genomic location on the expression of weak and strong core promoters. (B) Amount of variance explained by core promoters and genomic locations, respectively, using linear models fit on weak and strong promoters separately. (C) All pairwise correlations (Pearson's r) between genomic locations for weak and strong core promoters. (D) Correlation (Pearson's r) between promoter activity measured on plasmids and promoter activity at loc2.
