摘要
Nearly precise excision of a transposon related to Tn10 from an Escherichia coli plasmid was used as a model to study illegitimate DNA recombination between short direct repeats. The excision was stimulated 100-1000 times by induction of plasmid single-stranded DNA synthesis and did not involve transfer of DNA from the parental to the progeny molecule. We conclude that it occurred by copy-choice DNA recombination, and propose that other events of recombination between short direct repeats might be a result of the same process.
