title: Conservative integration of bacteriophage Mu DNA into pBR322 plasmid.
abstract: In order to clarify the first step in Mu integrative recombination, we have infected a bacterial strain harboring the plasmid pBR322 and isolated Mu DNA in a supercoiled form associated with this plasmid. These structures show an association of Mu with PBR322 without any preliminary replication.
