title: An infrequent generation of catenated network of pBR322 in Escherichia coli.
abstract: It was demonstrated that Escherichia coli infrequently generates the catenated network of pBR322. This complex pBR322 form was detected when DNA molecules could hardly enter the agarose gel during electrophoresis and was found to comprise monomers and dimers of the plasmid.
