title: Utilization of two distinct modes of replication by a hybrid plasmid constructed in vitro from separate replicons.
abstract: A hybrid plasmid, pSC134, that codes for two distinct sets of replication functions has been constructed in vitro by ligation of EcoRI endonuclease-cleaved pSC101 and Col E1 plasmid replicons, and has been introduced into Escherichia coli by transformation. The replication properties of the pSC134 plasmid in DNA polymerase I-defective mutants or in the presence of chloramphenicol indicate that this hybrid plasmid can utilize the functionally distinct modes of replication specified by both of its parent replicons.
