| Method | "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." |
| Comments | "Five minutes of replication corresponds to ~180kb DNA replicated for each fork, ample time to give the observed spatial separation of two independent forks." From this one can infer a value of 600bp/s for the replication rate in vivo (180,000bp/300s). |
