Abstract

Cairn's type replicative intermediates of both the wildtype Clo DF13 plasmid and the copy mutant CLO DF13 cop3 were isolated by dye-buoyant density centrifugation. Replicative intermediates were linearized at the HpaI or Sa1I cleavage site, and examined with the electron-microscope. The data show that replication of both the Clo DF13 wild type plasmid and the Clo DF13 cop3 plasmid, initiates at about 2.8% on the physical map. Replication proceeds unindirectionally and counterclockwise on this map.
