A tiny helper lightens the maternal load

Article Abstract:

A study revealing a surprising and elegant solution that could help to coordinately destroy a large number of maternal mRNAs at the mid-blastula transition of early animal embryogenesis is presented. Hence, an examination on fish that lacked the miRNA processing enzyme Dicer both maternally and zygotically is presented to demonstrate that miRNAs are essential for early morphogenesis of zebrafish embryos.
