Autoradiographic studies on RNA synthesis and transport in the ovary ofHydrophilus olivaceus fabr. (Hydrophilidae,Polyphaga, Coleoptera)

Summary Autoradiographic studies using³H-uridine in the ovary ofHydrophilus olivaceus Fabr. show that nurse cells, the germinal vesicle and follicular nuclei play an important role in contributing RNA whereby the major portion of RNA comes from the nurse cells.I am grateful to Prof. P. S. Ramamurty, School of Life Sciences, University of Hyderabad, Hyderabad, India, for his constant inspiration during the tenure of the present investigation.
