upon digestion of isolated h1-containing chromatin of every tested type in a low ionic strength solution ( unfolded chromatin ) , a standard series of mononucleosomes ( mn ) was formed : the core particle , mn145 , and h1-containing , mn165 , mn175 , mn185 , mn195 , mn205 and mn215 ( the indexes give an approximate length of the nucleosomal dna that differs in these particles by an integral number of 10 bp ) .
