DNA 'scrunching' occurs as RNA polymerase selects a position to begin synthesizing RNA

A research collaboration that combines novel "big-data" informatics tools with expertise in basic biology has uncovered details of an essential process in life: how a crucial enzyme locates the site on DNA where it begins to direct the synthesis of RNA. This finding may aid in the discovery of new antimicrobial medicines, and the powerful technological approaches developed for this research may shed light on other essential cellular processes.
