||"Fluorescent C-terminal fusion-protein derivatives of E. coli
replisome components, expressed from their endogenous chromosomal promoters, were constructed and their phenotypes
assessed by growth, flow cytometry, and microscopy."
||"Foci appear either shortly after birth or shortly before birth in
a mother cell and are present for 65 min on average. Assuming
the times of appearance and disappearance of foci mark replication
initiation and termination, respectively, then this value
for S phase, determined for timelapse cells growing on slides,
is slightly longer than [researchers'] previous estimate of 55 min for cells
growing in the same liquid medium (Wang et al., 2005 BNID 109249)."
