Clearance of Parental Products,. Here, we will review functional and mechanistic aspects of clearance of selected parental factors from early embryos, including different types of maternal RNAs, proteins, erasure of chromatin features of maternal and paternal genomes, as well as consumption of yolk and elimination of paternal mitochondria.作者: monochromatic 時(shí)間: 2025-3-22 12:46 作者: ambivalence 時(shí)間: 2025-3-22 14:03

Localization in Oogenesis of Maternal Regulators of Embryonic Development,often relies on mechanisms of RNA localization to specific subcellular domains to define the identity of future developing tissues.
