Résumé : Template capacity of Xenopus egg RNA during embryonic development. The template capacity of the RNA extracted in toto from Xenopus laevis eggs has been measured throughout embryonic development. It is clear that the mature oocyte contains a very high quantity of template RNA. After maturation, and throughout the rest of embryonic development template activity remains at a constant level, approximately equal to that of the mature oocyte, i.e., about 5 % of the template capacity displayed by the phage MS2 RNA. The hypothesis of an anticipative messenger RNA synthesis during embryonic development is discussed. The fact that template activity remains constant under our experimental conditions may also be due to the use of a heterologous system. © 1969.
