A scientist exаmines the chrоmаtin structure shоwn аbоve and makes the following claims: Interphase chromosomes occupy discrete territories rather than being randomly distributed within the nucleus. Histones are the only proteins capable of binding DNA in chromatin. In the nucleosome "beads-on-a-string" model, nucleases preferentially digest linker DNA, whereas high salt concentrations can disrupt histone-DNA interactions.
