Abstract: | Cytochemical and autoradiographic studies on the ovaries of Labidura riparia indicate that the oöcyte is supplied with RNA synthesized in the nurse cell nucleus. There is no indication that the oöcyte synthesizes its own RNA. Neither DNA nor protein can be shown to enter the oöcyte from external sources. Although largely cytoplasmic, the incorporation of lysine into protein also localizes in the nucleolus of older oöcytes. |
