Webb15 juli 2001 · Theoretically, histone octamers could be moved by fast disassembly and reassembly on a neighboring DNA fragment. Alternatively DNA might be translocated relative to an intact octamer. This latter possibility is supported by an in vitro assay that monitors the relocation of a single histone octamer on a small DNA fragment. spa packages west chester oh
