Figure 1From: Adaptive regulatory substitutions affect multiple stages in the life cycle of the bacteriophage ϕX174Genetic map of ϕX174 including relevant sites regulating gene transcription. Note that the map has been linearized for clarity; ϕX174 has a 5,386 nt circular genome. PA, PB, PD indicate transcription promoters; TJ, TF, TG, TH indicate transcription terminators. A to H indicate genes, and genes B, K and E are in different reading frames from the genes with which they overlap. Bars below the map indicate lengths of transcripts found at 37°C. Based on [10, 13].Back to article page
