A bstract It was ascertained that thymidine‐ 3 H added exogenously is incorporated periodically into the nucleus of the fertilized and the artificially activated eggs of Pseudocentrotus, Temnopleurus and Anthocidaris . Eggs stimulated insufficiently with butyric acid did not show any enhancement of incorporation of thymidine‐ 3 H. However, repetition of an insufficient stimulation induced incorporation of thymidine to some degree, although no visible cortical changes occurred.
