方法：选用微球菌核酸酶（MCN）为染色质结构识别探针，经蔗糖密度梯度离心、凝胶电泳，可显示不同龄大鼠大脑染色质结构特征的变化。
Methods : Micrococcal nuclease ( MCN ) was used as the probe to study chromatin structure and agarose gel electrophoresis and sucrose density gradient centrifugation were employed to investigate the changes of cerebral chromatin structure in rats of different ages .
