What prevents oocyte to enter M phase? I am working on a meiotic cell division using Xenopus oocyte. I have taken some genomic DNA and after shearing it through a needle, coated a 100 nm beads to act as chromosome to see what would happen if I have extra chromosome in oocyte. when coated beads are injected into germinal vesicle of oocyte, and activate oocyte with progesterone, oocyte does not enter M phase. While, if I had uncoated beads, oocyte...
