Abstract
The cleavage map of the plasmid RK2 was determined for the five restriction endonucleases EcoRI, HindIII, BamH-I, SalI and HpaI. DNA has been inserted into several of these sites and cloned in Escherichia coli. Efforts to obtain derivatives of RK2 reduced in size by restriction endonuclease digestion of the plasmid were not successful and indicated that genes required for the maintenance of this plasmid in E. coli are not tightly clustered. An RK2 derivative possessing an internal molecular rearrangement was obtained by transformation with restriction endonuclease digests of the plasmid.Entities:
