characterization of native nuclei by new unharmful biophysical methods , coupled both with the determination of lower order structures in dna and isolated chromatin , by a variety of sophisticated physicochemical probes and with the intranuclear dna distribution monitored in situ by high resolution image analysis , recently , point to a unique organization of chromatin-dna from the secondary up to the quinternary level .
