The updated model transcribes longer, but fewer, mRNA molecules to maintain a slightly lower total mRNA mass. See also Figure S3. (A) Comparison of the distributions of mRNA lengths between simulations with and without operons. (B) Comparison of the distributions of the total number of mRNA molecules between simulations with and without operons. (C) Comparison of the distributions of the total mRNA mass between simulations with and without operons. In all panes, the reported values were taken from each simulated cell with a fully completed cell cycle (n=768 for simulations without operons, n=758 for simulations with operons). Dashed lines represent the mean values across each simulation set.
