[Circadian rhythm of poly A polymerase in chromatin and nucleoplasmatic extract of rat liver].
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.
