In the present work we extend and analyze the scope of our recently proposed stochastic model for transcriptional regulation. which considers an arbitrarily complex cis-regulatory system using only elementary reactions. Previously. we determined the role of cooperativity on the intrinsic fluctuations of gene expression for activating transcriptional switches. https://www.roneverhart.com/AMS-Neve-1073SPX-Single-Preamp-and-EQ-p33827/
