Elongation enhances spatial asymmetryA) Schematic of localization of source and sink. B) Mathematical modeling of the effects of varying cell length on the distribution of [R ∼ P] for σk = σp = 100/τd. (Inset) The ratio of [R ∼ P] between the two poles increases linearly with increasing cell length. C) At enzymatic rates close to the diffusion rate (σk=σp=1/τd), the difference in [R ∼ P] between the poles increases with cell length; the polar ratio also increases linearly with cell length however it is not affected as significantly as the difference between the poles (inset).
