Polyadenylylation and Transcription Following Fertilization ( sea urchin embryos

Polyadenylylated RNA from sea urchin embryos concomitantly labeled with [OHladenosine and [14Cluridine between fertilization and the four-cell stage was used to determine whether the RNA primers prerequisite to the massive polyadenylylation known to occur after fertilization are synthesized during oogenesis or subsequent to fertilization. Characterization… CONTINUE READING
