Maternal 3’UTRs: from egg to onset of zygotic transcription in Atlantic cod
Kleppe, Lene; Edvardsen, Rolf B.; Kuhl, Heiner; Malde, Ketil; Furmanek, Tomasz; Drivenes, Øyvind; Reinhardt, Richard; Taranger, Geir Lasse; Wargelius, Anna (Journal article; Peer reviewed, 2012-09-01)Background Zygotic transcription in fish embryos initiates around the time of gastrulation, and all prior development is initiated and controlled by maternally derived messenger RNAs. Atlantic cod egg and embryo viability ... -
