[Circadian rhythm of poly A polymerase in rat liver nuclei].
Isolated nuclei from the liver of rats maintained under daily scheduled conditions of light (12 hrs) and food (8 hrs) showed a peak of Mn2+-dependent poly (A) polymerase activity 6 hrs after the beginning of the feeding period, as shown by DNA dependent RNA polymerase B. In fasting animals the peak of poly (A) polymerase occurs at 18.00.
