Purpose of Mitosis
To create identical cells.
Interphase
The cell grows and replicates its DNA (S phase) before entering mitosis.
Prophase
The DNA condenses into chromosomes, microtubules appear, and the nucleolus disappears.
Prometaphase
The nuclear membrane breaks down, and microtubules attach to the chromosomes.
Metaphase
The chromosomes align at the center of the cell.
Anaphase
The sister chromatids separate and move to opposite poles of the cell.
Telophase
New nuclear membranes form around the chromosomes, and the chromosomes uncoil.
Cytokinesis
The cell divides into two daughter cells.
Karyokinesis
Nuclear Division
Interphase (90% of the cell cycle)
The cell grows and replicates its DNA (S phase) before entering mitosis.
Gap 1 (G1)
Rapid growth, performs normal cell functions, major portion of cell life.
Synthesis (S)
DNA is copied.
Gap 2 (G2)
Nucleus prepares to divide, molecules for cell division are produced, centrosomes appear containing two centrioles.
Telophase (Cytokinesis)
Cell membrane splits, the nuclear membrane reappears in both cells, and two identical cells form.
Mitosis
Produces identical body cells (not reproductive cells, which involve meiosis).
Prophase
Chromosomes condense and become visible, and the nucleus begins to disappear.
Metaphase
Chromosomes align in the cell’s center.
Anaphase
Chromosomes separate and move to opposite cell poles with spindle fibers.
Telophase
New nuclei form around chromosome sets on each side.
Cytokinesis
Splits the cytoplasm, completing cell division.
Mitosis
Process where cells divide to produce two identical daughter cells.
Mitosis
Essential for growth, healing, and cell replacement.
Prophase
DNA condenses into chromosomes, centrosomes move to opposite ends of the cell.
Anaphase
Chromosomes split and move to opposite poles.
