the h-chain gene sequences in the middle silk gland nuclei or the posterior silk gland nuclei from the fourth molting stage are cleaved partially into nucleosome dimer to oligomer sizes upon digestion with higher concentrations of micrococcal nuclease , suggesting that the inactive forms of the h-chain gene chromatin are constructed by folding of the chromatin fiber containing a regular array of nucleosomes .
