WebA) The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile phospholipids. B) Plant cells deposit vesicles containing cell-wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

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 … WebAt this moment, termed metaphase, all kinetochores have typically captured microtubules leading to satisfaction of the spindle-assembly checkpoint, but the cell does not enter anaphase immediately. The waiting time in metaphase is related to the kinetics of securin and cyclin B1 degradation, which trigger sister-chromatid separation and promote ... hester jane homan mulock
