 mitosis Interface: this is the longest period of the complete cell cycle during, witch the dna replicates the centrioles divide and the protiens are actively produced. Prophase:(first mitic stage) the nucleolus fades and condenses into chromesomes, each chromesome comprises two chromatids. microtubules of a cytoskelton disosemble Prometaphase: nuclear envelope breaks down and there is no longer a reconizable nucleus some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores. protien bundles at the centromere region, on the chromosomes where sister chromatids are joined. Metaphase: the tenshion applied by spindle fibers aligins chromosomes in one plane at the center of the cell. Anaphase: spindle fibers shorten the kinetochores seperate, the chromatids are pulled apart and begin moving to the cell poles.
