Figure 34-3: Structures of the PY54 plasmid ends. A. Nucleotide sequence of the DNA region upstream from the tel gene (AJ348844). The 42 bp palindrome, its flanking 15 bp inverted repeat and the putative start codon, ribosome binding site (RBS) and putative promotor sequences of the tel gene are boxed. B. DNA sequences of the right and left plasmid ends.
