More precise maps of the model organism could provide interesting new insights into higher organism biology. The study, carried out by researchers from Pennsylvania State University (PSU; PA, USA) and Cornell University (NY, USA), saw ChIP-exo/seq used to map the precise binding sites of over 400 Saccharomyces cerevisiae chromosomal proteins that interact with the genome – some at only a few locations, some at thousands. “When I first...
