Mitosis is the cell process where a cell divides into two cells each containing identical genetic material to one another. Mitosis proceeds in a series of phases.Answer and Explanation: The metaphase plate is the region where the double-stranded chromosomes will line up during the metaphase stage...

(a vesicular structure) at the metaphase plate. There, the vesicles fuse and coalesce from the center toward the cell walls; this structure is called a cell plate. As more vesicles fuse, the cell plate enlarges until it merges with the cell walls at the periphery of the cell. Enzymes ...
Incubation of mouse oocytes with OA leads to lengthening of mitotic spindles, disorganization of the metaphase plate, and phosphorylation of proteins associated with MTs (24). These results imply that protein phosphatases are necessary for dephosphorylation of MAPs, resulting in increased MT assembly ...

the plasma membrane at the former metaphase plate. The actin filaments pull the equator of the cell inward, forming a fissure. This fissure, or “crack,” is called thecleavage furrow. The furrow deepens as the actin ring contracts, and eventually the membrane is cleaved in two (Figure 4)...
Mitosis relies on forces generated in the spindle, a micro-machine composed of microtubules and associated proteins. Forces are required for the congression of chromosomes to the metaphase plate and their separation in anaphase. However, besides forces,
