^*The total number of sugar molecules present in the medium in the experimental setup of Kremling et al. (2001) was divided by the total number of cells. The volume of the cell and the cell density were set to 10⁻¹⁵ L and 280 g/L, respectively.

^†The mean and standard deviation of the number of protein molecules at the beginning of the 10th bacterial generation.
