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.

Cell Cycle• The dividing and non-dividing stages in

the life of a cell.• Phases:

Interphase: growth and DNA replication

1. Prophase

2. Metaphase

3. Anaphase
