(a) The 100-minute genetic map of E. coli. Genes of bacterial operons (discussed in Section 12.2) are boxed. The origin of replication (oriC) is seen at 84 minutes. (b) A 2.5-minute segment (minutes 42.5–45) of the E. coli time-of-entry map in comparison with a segment of approximately 500,000 base pairs of the E. coli genome derived from E. coli genomic sequencing. Selected genes between 42.5 minutes and 45 minutes on the time-of-entry map (upper) are aligned with their positions in the genome sequence map (lower) to illustrate the compatibility of the two mapping approaches(a) The 100-minute genetic map of E. coli.
