Mature oocyte nucleus (center) shows no uptake; scale is 12 microns. FIGURE 5. Embryos pulsed with 3H-TTP for 1 hour and fixed in late cleavage-early blastula stages, showing heavy nuclear uptake. Mature oocyte is without label; scale is 15 microns. FIGURE 6. Light label over nuclei of swimming blastulae hours after 1 hour pulse chase with 3H-TTP in the 4 cell stage; scale is 14 microns.
