Construction of Chimeric Phages and Plasmids Containing the Origin of Replication of Bacteriophage Lambda

Abstract
Segments of the replication control region of bacteriophage lambda (lambda) and lambda mutants defective in replication were attached in vitro to the phi80 phage vector Charon 3 and to the plasmid vector mini Col El (pVH51). The chimeric phages and plasmids have been used to localize the origin of lambda DNA replication and to facilitate a structural analysis of the lambda replicator.
