the size and solubility properties of the repeated c-c-c-c-a-a dna nucleoprotein complex after micrococcal nuclease digestion of macronuclei are clearly distinguishable from those of nucleosomes , and it is inferred that this dna sequence in macronuclei is packaged in chromatin by proteins other than histones .
