Nonrandom F-plasmid replication in Escherichia coli K-12.

RESUMO
Both the autonomous and chromosomally integrated F plasmids were found to replicate in a nonrandom fashion after a density transfer from heavy medium ([13C]glucose, 15NH4) to light medium ([12C]glucose, 14NH4). The data are consistent with the hypothesis that both the chromosome and the F plasmid are replicated in a cell cycle-specific manner. Thus, these data support the proposal (J. D. Keasling, B. O. Palsson, and S. Cooper, J. Bacteriol. 173:2673-2680, 1991) that plasmids replicate in a cell cycle-specific manner.
