Structures of the wild-type (a) and duplicated (b) regions of E. coli BN1004. The HindIII site within ogt is illustrated, as are the primer hybridization sites used to delimit the extent of duplication. The 12-bp direct repeat sequences within abgA and fnr are illustrated. It can be seen from panel b that only primer pair pri1-pri2 could yield a PCR product from DNA containing a duplication. The source of the 4.2-kb HindIII fragment containing abgT is also evident.
