The researchers found that the nucleosomes within chromatin fibers form short stacks that quickly fall apart and reform within a matter of milliseconds. (sciencedaily.com)
Indeed, the interspersion of these two types of nucleosome has been observed on stretched chromatin fibers of both Drosophila [16] and maize [10]. (genomebiology.biomedcentral.com)
Together, the discovery of such rapid dynamic modes within chromatin fibers provides new insight how processes can gain access to the DNA (or are prevented to do so), such as transcription factors, or the machinery for transcription, replication or DNA repair. (sciencedaily.com)
