Diurnal rhythmicity of nuclear and cytoplasmic polyadenylylated ribonucleic acids and or polyadenylate-dependent polyadenylate polymerase in rat liver.
The hepatic concentration of polyadenylylated RNA was measured in rats kept under LD 12:12. In the nuclei, the concentration was maximal during the dark phase, whereas in the cytoplasm, the highest values were measured during the light phase. The activity of nuclear polyadenylate-dependent polyadenylate polymerase showed a rhythm of low amplitude with a maximum at light-off.
