    Chromatin remodeling is a key mode of transcriptional regulation, and studying the nucleosome positioning at promoters is an important means to understand how genes are regulated. Nucleosome scanning is a convenient method to study nucleosome positioning. Yeast cells are converted to spheroplasts and nuclei are isolated. The nuclei are then digested by micrococcal nuclease to yield mononucleosome-sized
    DNA
    . Using a set of overlapping primers that cover the entire promoter, quantitative real-time
    PCR
    is performed using the mononucleosome DNA as the template. The nucleosome enrichment for each primer is calculated to yield a map of nucleosome occupancy across the promoter.
