Rat neuronal identifier (ID) elements are located in chromatin regions that are organized in nucleosomal structures in both neuronal and non-neuronal cells. A subpopulation of ID sequences in chromatin of liver and kidney cells are relatively resistant to micrococcal nuclease digestion and are organized in nucleosomes exhibiting an atypically short repeat length. Other repetitive elements do not show this organization.
大鼠神经元标识符（ID）元件位于染色质区域，这些区域在神经元细胞和非神经元细胞中均以核小体结构组织。肝细胞和肾细胞染色质中的ID序列亚群对微球菌核酸酶消化相对抗性较强，并以重复长度异常短的核小体形式组织。其他重复元件则不显示这种组织形式。
