The recruitment model for gene activation stipulates that an activator works by bringing the transcriptional machinery to the DNA. Recent experiments in bacteria and yeast indicate that many genes can be activated by this mechanism. These findings have implications for our understanding of the nature of activating regions and their targets, and for the role of histones in gene regulation.
