Cell Division By: Courtney Ayers

The Three Stages of Cell Division

Interphase Mitosis Cytokinesis

Interphase

is the phase of the cell cycle in which the cell spends the majority of its time, it grows DNA replicates, and prepares to divide.

Mitosis

is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components

Cytokinesis is the process in which the cytoplasm of a single

eukaryotic cell is divided to form two daughter cells and is the division of cytoplasm.

The 4 stages of Mitosis

Prophase Metaphase Anaphase Telophase

Prophase

Nuclear membrane + nucleolus disappears, spindle fibers appear and the chromatin condenses into double rod-shaped structures called chromosomes.

Metaphase

It’s DNA, duplicated chromosomes move to the middle, and sister chromatids on either side.

Anaphase

is the stage of mitosis when sister chromosomes move to opposite poles of the cell.

Telophase

Nuclear membrane + nucleolus reappear, chromosomes loosen up, and they become chromatin.

Interphase is the phase of the cell cycle in which the cell spends the majority of its time, it grows DNA replicates, and prepares to divide.

prophase Nuclear membrane + nucleolus disappears, spindle fibers appear and the chromatin condenses into double rod-shaped structures called chromosomes.

Metaphase duplicated chromosomes move to the middle and sister chromatids are on either side.

Anaphase is the stage of mitosis when sister chromosomes move to opposite poles of the cell.

Telophase Nuclear membrane + nucleolus reappear, chromosomes loosen up, and they become chromatin.

Cytokinesis is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells and is the division of cytoplasm.
