... and beyond. We focus on a modern interpretation of this concept in terms of information theory, largely centered on its application to cell specification in the early Drosophila embryo. We argue that a true physical variable (position) is encoded in local concentrations of patterning molecules...

...Neta Rahimi; Inna Averbukh; Shari Carmon; Eyal D. Schejter; Naama Barkai; Ben-Zion Shilo ABSTRACT Establishment of morphogen gradients in the early Drosophila embryo is challenged by a diffusible extracellular milieu, and by rapid nuclear divisions that occur at the same time. To understand how...
