Spontaneous access to DNA target sites in folded chromatin fibers

DNA wrapped in nucleosomes is sterically occluded from many protein complexes that must act on it; how such complexes gain access to nucleosomal DNA is not known. In vitro studies on isolated nucleosomes show that they undergo spontaneous partial unwrapping conformational transitions, which make the...
