stages of mitosis
hunter turner
prophase
condense and becomes visible in the light microscope as chromosomes. nucleolus disappears
prometaphase
nuclear membrane dissolves marking the beginning of prometaphase. proteins attafch to the centromeres creating the kinetochores
anaphase
the paired chromosomes seperate at the kinetochores and move to opposite sides of the cell
telophase
chromatids arrive at the opposite poles of the cell and new membranes form around the daughter nuclei.
cytokinesis
in animal cells cytokenesis results when fiber ring composed of a protein called actin around the center of the cell contracts pushing the cell into two daughter cells, each with one nucleus
