The Four Phases of Mitosis Explained
Overview of Mitosis
- Mitosis is a continuous process divided into four distinct phases.
- Each phase is characterized by specific cellular activities.
Phases of Mitosis
1. Prophase
- Centrioles located outside the nucleus divide.
- The nuclear material condenses into visible chromosomes.
- The nuclear membrane disappears.
- Formation of spindle fibers as centrioles extend long, thin strands.
2. Metaphase
- Chromosomes align along the equatorial plane of the spindle.
3. Anaphase
- Chromatids separate and migrate to opposite ends of the cell.
- Once separated, chromatids are termed chromosomes.
- A complete set of chromosomes moves toward each centriole.
4. Telophase
- The cell completes division.
- Chromosomes begin to uncoil.
- New nuclear membranes form around each set of chromosomes.
- Spindle fibers disappear.
- Two identical cells enter their growth phase.
Additional Information
- Mitosis is crucial for cellular replication, ensuring each new cell receives an identical set of chromosomes.
- This process is fundamental for growth, tissue repair, and asexual reproduction in organisms.
