Finished mitosis by dividing the cytoplasm and organelles of the original parent cells into two separate daughters cells
During_____, the cell carries out its normal functions and the chromosomes are thinly spread out though out the nucleus.
Looking through a light microscope at the dividing cell, you see two separate groups of chromosomes on opposite ends of the cell. New envelopes are taking shape around each group. The chromosomes then begin to disappear as the unwind. You are witnessing _______.
