STAGES OF MITOSIS
What is Mitosis?
• Mitosis is a cell division that results in two daughter cells having the same number and kind of chromosomes as the parent cell.
Prior to Mitosis:
INTERPHASE
Steps in Interphase• The longest phase in
which the cell is dormant.
• Cell gets ready to go through cell division.
• Chromosome number doubles.
Phase 1 of Mitosis
PROPHASE
Steps in Prophase
• Centrioles move to opposite ends of the cell.
• A spindle develops.• The nuclear
membrane breaks down.
*Chromosomes PAIR up.*
Phase 2
METAPHASE
Steps in Metaphase
• Chromosomes move to the MIDDLE of the cell and line up.
Phase 3
ANAPHASE
Steps in Anaphase
• Chromosomes MOVE APART to opposite ends of the cell along the spindle.
Phase 4
TELOPHASE
Steps in Telophase
• Chromosomes begin to uncoil.
• The nucleolus reappears.
After Mitosis
CYTOKINESIS
Steps in Cytokinesis
• The cytoplasm divides forming two new cells.
• The cell membrane reforms around the new cells.
