Cytokinesis microscope
WebJul 30, 2024 · In eukaryotes, this generally occurs by the process of mitotic cell division, which involves the separate but often coordinated processes of cytokinesis (division of the cytoplasm and organelles) and mitosis (division of the nucleus and associated DNA). WebCytokinesis begins--formation of daughter cells. In animals, like the whitefish, a cleavage furrow, a contractile ring of muscle like fibers, pinches the cell into two. The nuclear envelope forms again around the nuclei. Whitefish Mitosis Practice The photomicrographs below show sections of whitefish blastula.
