Abstract excerpt
Derivatives of plasmid pBR327 with the tet gene interrupted by 165 pb or 401 bp direct repeats were constructed. In cells harboring these plasmids, deletions which restored the wild-type tet gene gave rise to tetracycline-resistant colonies, thereby allowing a simple phenotypic test for deletion formation. The frequencies of deletions in these plasmids were measured in Escherichia coli strains proficient or...
