The restriction–modification genes of Escherichia coli K-12 may not be selfish: They do not resist loss and are readily replaced by alleles conferring different specificities
Type II restriction and modification (R-M) genes have been described as selfish because they have been shown to impose selection for the maintenance of the plasmid that encodes them. In our experiments, the type I R-M system EcoKI does not behave in the same way. The genes specifying EcoKI are, howe...
