PRJDB2994 Directional RNA-seq of mouse oocytes and embryos In mice, zygotic activation mainly occurs on a wide variety of genes mainly at the 2-cell stage. Long noncoding RNAs (lncRNAs) are increasingly being recognized as molecules that modulate gene expression. In this study, we performed the directional RNA-seq of MII oocytes and 2-cell embryos to identify the long noncoding RNAs activated during ZGA.
