Abstract

3H arginine and 3H lysine were incorporated by the nuclei of Xenopus oocytes and ova, but the cytoplasm of oocytes only took up arginine, and that of the ovum, neither of them. On correlating this finding with histochemical results, it was inferred that the cytoplasm of the mature ovum is saturated with basic proteins. In the Xenopus testicle, the histone precursors were incorporated by the spermiogenetic stages, but not by Sertoli cells. The histochemical reactions of basic proteins were more pronounced in the cytoplasm than in the nucleus of mature and maturing ova.
