Cell Cycle Phases
Cell Cycle Phases
The life cycle of a cell, consisting of interphase and mitotic phase.
Mitosis Purpose
Mitosis Purpose
Cell division resulting in two identical cells containing the same number of chromosomes.
Mitosis Prophase
Mitosis Prophase
Chromosomes condense, spindle fibers appear, nucleus disappears.

Study Notes
Cell Cycle
- Cell cycle: the life cycle of a cell, from cell division to the next cell division.
- Two phases: interphase and mitotic phase
Cell Division
- Cell division: occurs when an organism needs to grow larger or replace dead/damaged cells.
Mitosis
- Mitosis: the DNA or chromosomes divides and separates into 2 identical nuclei.
- Four phases of mitosis:
- Prophase: the chromatin condenses into X-shapes, spindle fibers form from centrioles, and the nucleus disappears.
- Metaphase: chromosomes align along the center of the cell, centrioles reach opposite sides of the cell.
- Anaphase: chromosomes separate and are pulled to opposite sides of the cell.
- Telophase: chromosomes unite on each side of the cell, forming two nuclei
Mitosis Results
- Result of mitosis: an exact copy of the original cell (same number of chromosomes).
Cytokinesis
- Cytokinesis: after mitosis, the cell physically divides into two separate cells.
