Comments p.364 4th paragraph:"Moreover, because proteins can diffuse the typical length of a bacterial cell (∼2 μm) in 1 s or less (given typical diffusion coefficients D = 1–10 μm^2/s), there is generally no need for active mechanisms to assist factors in finding their target landmarks." "At the simplest level, a landmark is simply an object—such as a protein, lipid, or polymer—that already has a defined spatial distribution in the cell."
