title: A mechanism for stochastic decision making by bacteria.
abstract: What mechanism underlies the induction of the lac operon? Expression from the lac operon is an all-or-none phenomenon. Recent work by Choi et al. combines single-molecule imaging of gene expression with single-cell induction measurements to develop a stochastic model describing the critical role of single lac-repressor molecules in induction.
