Figure 22-1: Genetic and transcriptional maps of f29, B103 and GA-1 DNA. The maps are aligned with respect to the A2c, A2b and A3 promoters. The direction of transcription and length of the transcripts are indicated by arrows. The positions of genes 16.7 and 17 are indicated. ORFs 16.9, 16.8, 16.6 and 16.5 are indicated by the numbers .9, .8, .6 and .5, respectively. Transcriptional terminators are indicated by stem-loop structures. The grey box indicates the DNA region encoding the pRNA, and the black box indicates the region containing the early promoters A2c and A2b, and the late promoter A3. The figure is adapted from Meijer et al. (90).
