Abstract
Chromatin preparations from the liver of rats accustomed to eating during the first 8 hrs of a daily 12 hrs dark period exhibit the same fluctuations of poly (A) polymerase as whole nuclei (a peak at 15.00 in fed rats, a peak at 18.00 in fasting ones). Nucleoplasmic activity was detectable only on addition of exogenous primer.
摘要
来自习惯在每日12小时黑暗期的前8小时进食的大鼠肝脏的染色体制剂，其多聚（A）聚合酶的波动与完整细胞核相同（喂食大鼠在15:00出现峰值，禁食大鼠在18:00出现峰值）。仅在添加外源引物后才能检测到核质活性。
