||P.5 top paragraph: "Validating predicted changes in fork velocity and initiation capacity using time-resolved profiling: [Investigators] next wished to verify predicted changes in fork velocity or initiation capacity. This required an independent means for measuring these parameters. To this end, [they] profiled cells that progress synchronously through S phase. Cells were arrested at the end of G1 using α-factor, and were followed for sixty minutes upon release, with samples taken every three minutes for DNA sequencing. Synchronized progression was verified by DNA staining (Fig. 4A). Plotting DNA content as a function of chromosomal coordinates at different times showed the expected v-shape increase in DNA content around replication origins, capturing the symmetric progression of the replication fork (Fig. 4B)."
||P.5 top paragraph: "Based on this pattern around well-characterized origins [see Measurement Method], [investigators] estimated wild-type fork velocity to be 2.3 kb/min, consistent with previous estimates (1.6-3 kb/min)(primary sources)."
