Determination of deoxyribonucleic acid replication time in exponentially growing Escherichia coli B/r.

G Churchward, H Bremer
PMCID: PMC235344  PMID: 324977

Abstract

The time necessary to replicate the chromosome (C period) was measured in Escherichia coli B/r (ATCC 12407) and a low-thymine-requiring derivative of that strain. In the Thy- strain, C was measured as a function of growth rate and exogenous thymine concentration either from step-up or chloramphenicol experiments. In the Thy+ parental strain, C was measured only as a function of the growth rate and only by the chloramphenicol method. The C period was found to decrease with growth rate and, in the Thy- strain, the C period also decreased with increasing thymine concentration. It approached a value of approximately 37 min at high growth rates.
