  • Title: The RNA of unfertilized sea urchin eggs is "capped".
    Author: Pirrone AM, Spinelli G, Acierno P, Errera M, Giudice G.
    Journal: Cell Differ; 1977 Mar; 5(5-6):335-42. PubMed ID: 558057.
    Abstract:
    It is shown that the RNA of unfertilized sea urchin eggs is active in stimulating protein synthesis in a wheat germ cell free system. This activity is not lowered by conditions that inhibit the methylation processes but is inhibited by a treatment that damages the "cap", A difference in activity in a wheat germ cell free system between the RNA of unfertilized eggs and the RNA from early embryos is described.
