The procedure was carried out in M2 medium Sigma supplemented with 0.2 mM of the cyclic nucleotide phosphodiesterase inhibitor 3 Isobutyl 1 methylxanthine IBMX Sigma to prevent the oocytes from further progress to germinal vesicle breakdown GVBD. The cumulus cells were gently removed by pipetting and the oocytes were briefly exposed to acidic Tyrode's solution Sigma to remove the zona pellucida followed by three washes in M2 medium. For mouse MII oocyte collection 4 wpf 5 wpf C57BL6/N females were injected with 5 U of PMSG followed by 5 U of human chorionic gonadotropin hCG 45 hours later. The oviducts were dissected 20 22 hours later and transferred to a clean dish containing M2 medium. The oviduct ampulla was identified under a stereomicroscope to isolate MII oocytes containing the cumulus mass. The oocytes were treated with 0.3 mg/ml hyaluronidase dissolved in M2 medium to remove the cumulus cells and then exposed to acidic Tyrode's solution for a few seconds to remove the zona pellucida followed by three washes in M2 medium. For mouse early embryo collection 8 wpf C57BL/6N females were superovulated by hormone injection 5 U PMSG followed by 5 U hCG 45 hours later and transferred to cages with 8 wpf C57BL/6N males for mating.

Embryos were flushed from the reproductive tract into HEPES buffered CZB medium then transferred to acidic Tyrode's solution for a few seconds to remove the zona pellucida followed by three washes in M2 medium.", "For zebrafish bulk zygote samples total RNA was extracted from 100 zebrafish zygotes using TRIzol\u2122 Reagent and eluated in 100 \u03bcl of RNase free water. Then 10 \u03bcl and 5 \u03bcl samples were taken for 10 zygote and 5 zygote samples respectively and volumes were adjusted to 12 \u03bcl with nuclease free water. For zebrafish single zygote samples single zygote was manually picked and distributed into 12 \u03bcl of 1X Lysis buffer Takara. For the polyA selected RNA samples of mouse liver and embryonic stem cell WT and Mettl3 KO total RNA was extracted using TRIzol\u2122 Reagent Thermo Fisher Scientific and PolyA+ RNA was selected twice by Dynabeads\u2122 mRNA Purification Kit Thermo Fisher Scientific. For mouse embryonic stem cell samples the cells were sorted into 12 \u03bcl 1X Lysis buffer using BD FACSMelody\u2122 Cell Sorter BD Biosciences. For mouse oocyte and embryo samples post three washes in M2 medium oocytes and embryos were manually picked and put into 12 \u03bcl 1X Lysis buffer.
