Web• State the key functions of cell division. • Understand why cell division results in genetically identical cells. • Outline the stages in the cell cycle including interphase (G1, S, G2) mitosis and cytokinesis. • Describe the events that occur in the phases of mitosis (prophase, prometaphase, metaphase, anaphase and telophase. WebOct 4, 2024 · Prometaphase – The stage immediately preceding metaphase, in which the nuclear membrane breaks down. Anaphase – The stage immediately after metaphase, when the chromosomes are separated. Metaphase Plate – The imaginary line in the middle of the cell that chromosomes align on during metaphase.

http://www.biology.arizona.edu/cell_bio/tutorials/cell_cycle/cells3.html Prometaphase is the phase of mitosis following prophase and preceding metaphase in eukaryotic somatic cells. In prometaphase, the nuclear membrane breaks apart into numerous "membrane vesicles," and the chromosomes inside form protein structures called kinetochores. Kinetochore microtubules emerging from the centrosomes at the poles (ends) of the spindle reach the chromosom…
