the investigation of the dna folding in the oligonucleosome chains with increasing ionic strength has shown complete invariability of the dna compactness in the ascitic chromatin up to 100 mm nacl , while in liver nucleosomes an additional folding of the linker portion of the dna was observed within the range of 20-40 mm nacl .
