The maternal genome inherited … Web23 de jun. de 2024 · Transition from oocyte to zygote involves mRNA translation, which is essential to start a new life and organelle remodeling. Studies suggest that meiotic machinery molecules regulate oocyte to zygotic transition. After this transition, the zygote starts to divide mitotically and develop into a multicellular organism.
