Comments p.1602 right column bottom paragraph: "Considering the fast transcription (∼45 bases/s) and translation (∼15 residues/s) rates, [investigators] tentatively assign 1/κ to the fluorophore maturation process (SOM Text). Although [they] can only spatially resolve a few molecules within an E. coli cell because of the diffraction limit, the long spread of the stochastic arrival times of Venus allows many more protein molecules per expression burst to be counted in several consecutive images."
