After the resumption of meiosis and fertilization, differentiated oocytes dramatically change their nature to generate totipotent zygotes. However, since transcription does not occur in oocytes and early 1-cell stage embryos, gene expression is controlled only by post-transcriptional regulation. There are huge mRNAs stored in full-grown oocytes (FGO). A part of them is not translated in FGO and MII stage oocytes, and become translated after the resumption of meiosis and fertil...
