Metaphase nuclear membrane

Webnuclear envelope breaks down; nucleolus disappears; Metaphase. Metaphase is so named because the chromosomes line up in the middle of the cell. The centromeres attach to … WebBACKGROUND: Cytoplasmic defects are thought to cause aneuploidies in oocytes and embryos and oocyte ‘reconstruction’ by germinal vesicle (GV) transfer may circumvent such defects. In mice ‘reconstructed’ oocytes undergo meiosis and fertilize normally, but early embryonic development is compromised if their ooplasm matured in vitro. This study …
