Following fertilization, activation of a complex developmental program requires the differential expression of key genes. In most metazoa, the prevailing view is that early differential gene expression occurs primarily through post-transcriptional regulation of maternally deposited products in the oocyte. Two novel studies published from the Rajewsky laboratory in this issue of The EMBO Journal...
