Figure 39-2: Genomic organisation and transcription map of fC31. The genome is represented by a line, broken at the middle, with the left arm (upper section) and the right arm (lower section). The ends represent the cohesive (cos) ends of the linear genome. The genes are represented by boxes, some of which are numbered, with the late genes in grey, early genes white, and immediate early genes (repressor, c; integrase, int; gene 32) black. The putative activator, gene 12, is represented by a stippled box. The arrows below the genome represent transcripts; black are early or immediate early and grey are late. The dotted lines are putative transcripts that have not been directly observed by S1 mapping. The positions of early promoters (black arrowheads), late promoters (grey arrowheads), immediate early promoters (bent arrows) and terminators (stem-loop icons) are shown. Diamonds represent the repressor binding or CIR sites.
