The study reveals two distinct gene regulatory architectures, expanding the traditional model of gene regulation. So-called constitutive genes, those that perform basic housekeeping functions and are nearly always active at low levels require only a basic set of regulatory controls; whereas those that that are activated by environmental signals, known as inducible genes, have a more specialized architecture. This finding in yeast could open the door to a better understanding of the
