Autoradiographic Study of Uptake of Tritiated Glycine, Thymidine, and Uridine by Fruit Fly Ovaries

R. C. KING 1 and R. G. BURNETT 1

1 Northwestern University, Evanston, Illinois

Synthesis of DNA occurs in the nurse cell nuclei of Drosophila melanogaster in an asynchronous manner, whereas synthesis of RNA occurs in all these nuclei simultaneously. Synthesized RNA is concentrated in the plasmosomes; subsequently nuclear RNA enters the cytoplasm of the nurse cell and eventually the oöplasm. Protein synthesis occurs in the nucleoplasm and cytoplasm of all the cells in the egg chamler.
