Figure 9-1: Genetic map of regulatory region of l (not drawn to scale). Shown are relevant, promoters (P), operators (O), terminators (t, filled squares intrinsic and filled circles Rho-dependent), nut (put), and qut. Below are shown transcription patterns in the absence and presence of N and Nus factors and in the presence and absence of Q. Narrowing of lines provides an indication of reduced levels of transcription. See text for details.
