Contiguous plasma membrane of the oocyte and NC. (A) EM of an entering NC nucleus. Cartoon indicates position in egg chamber. (B) Dashed red-lined box in A imaged at higher magnification with traced plasma membranes (PM) of follicle cells (green), contiguous plasma membranes of oocyte and NC (red), and nuclear membrane of entering NC (blue). (C) Red-lined box in B imaged at higher magnification. (D) Red-lined box in C imaged at higher magnification. Scale bars: 5 µm (A and B); 1 µm (C); 0.25 µm (D).
