Conditions of Use
chromisomes duplicate them selves. both of them move to the oposite side of of the cell wall. the cell elongates and its plasma membrane grows in ward. then after after the cell splits in half, the cell divides and creates two sister cells. thoose cells are able to work because, the mom cell provides everything they need to produce and survive.
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.
