mRNA and RP depths in differentially translated operons. The mRNA and RP depths of each genome position are shown as gray area and red line, respectively, on a 1-kb scale. The position of each gene is shown as a thick arrow below (A). The ilvG gene with or without a frameshift mutation is highlighted in blue (B and C, respectively). The R/m ratio of each gene is shown inside arrows (D–I), and genes with low R/m ratios are marked with an asterisk next to their name and shown in blue.
