RADIOAUTOGRAPHIC EVIDENCE FOR THE INCORPORATION OF LEUCINE-CARBON-14 INTO THE MITOTIC APPARATUS.
Mitotic apparatus isolated at metaphase from sea urchin eggs, and placed in sea water containing leucine-carbon-14 after fertilization, has been shown by radioautographs to have taken up carbon-14 in such a way that it is not removable by repeated washing, by "chasing" with leucine-carbon-12, or by treatment with hot trichloroacetic acid.
