Comparison of reads of cas2 and its downstream RNA of M. tuberculosis WT and ΔcnpB analyzed using the Rockhopper program. Expression from both the positive strand (blue) and the negative strand (red) of the WT and ΔcnpB strains, respectively, is shown. The translational stop codon of cas2 is indicated with an arrow. The sequence of the first repeat in the complement orientation is indicated. DEG, differentially expressed genes; operons, multigene operons; UTRs, untranslated regions.
