Before revision:  Our model also predicts the variability in cell sizes is independent of growth temperature between 22^o and 42^oC. To test the model, we perform experiments with E. coli strains mutant for recA, sulA and slmA, factors known to affect replication fork dynamics and coupling to cell division.
