Chromosome replication and cell division in plasmid-containing Escherichia coli B/r.

Abstract

The kinetics of chromosome replication and cell division have been examined in recA mutants of Escherichia coli B/r containing F' plasmids of various sizes. Plasmid-mediated alterations in growth properties were detected only with the presence of the larger F' plasmids, and were reflected in decreased mean cell sizes and growth rates. The lengths of C and D in all plasmid-containing strains were in accord with the values for plasmid-free parental strains growing with similar generations times. The findings were consistent with an absence of competition between the chromosomal and extrachromosomal replicons for rate-limiting components involved in the initiation of deoxyribonucleic acid synthesis or in the elongation of deoxyribonucleic acid chains.
