the local chromatin structure of this region correlates with tissue-specific kappa gene expression : it is resistant to nucleolytic digestion in the inactive kappa genes of murine brain and liver nuclei , but becomes uniquely sensitive to cleavage by deoxyribonuclease i or by a variety of restriction endonucleases in the chromatin of kappa-producing cells .
