stages of mitosis

hunter turner

interphase

preparing and engaged in the activity

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

metaphase

spindle fibers align the chromosomes along the middle of the cell nucleus.

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
