Abstract excerpt
A set of plasmids containing 42, 21 and 31 bp direct repeats was used to analyze the effect of repeat length on the frequencies of deletion formation and the structure of the deleted derivatives of different recombination-deficient Escherichia coli strains. Agarose gel electrophoresis of plasmid DNA demonstrated that the formation of deletions in these plasmids was associated with dimerization of plasmid DNA....
