Exploiting bacterial growth laws to characterize indirect mechanisms for generating phenotypic heterogeneity from isogenic populations

From the time of Jacob and Monod, a dominant theme running through microbiology and bacterial physiology is the idea that the information encoded in DNA can be connected to the physiological state of the organism through a multi-scale assembly of simple elements: the gene within an operon, the operon within a network and the network within the cell. This bottom-up approach to the understanding (and, more recently, the synthesis) of genetic networks is analogous to the engineering principles of electrical circuit design - a fruitful analogy that has lead to significant conceptual advances particularly in the burgeoning field of systems biology. But the limitation of this analogy is, of course, that electrical circuits do not grow and divide.
