72 hours (8 cells) (BEFORE BLASTOCYST STAGE) - what is the human MZT Mid-blastula transition/maternal-zygotic transition - when the transcription of zygotic genes begins and maternal mRNAs are degraded, the cell cycle lengthens, gap stages are added (before is only M and S) and the synchronicity of cell division is lost. - embryo runs on maternal resources (mRNAs and proteins in the egg @ time of fertilization) until this. is when maternal effect genes are turned off. gap genes - organ...
