Figure 6.

The cell cycle of a wild-type daughter cell in glucose medium. Cell size (mass) increases exponentially (mass-doubling time=90 min). The cell divides at a size of 2.37 (arbitrary units) into a smaller daughter cell (size=1.09) and a larger mother cell (size=1.28). Following the time-course of daughter cells over three generations, we plot the rise and fall of certain key cell cycle regulators in a, b. The cycle time of daughter cells in this simulation is 100 min. One arbitrary unit of cell size=33pg=30 fL.
