MITOSIS by Mind Map: MITOSIS

1. TELOPHASE

1.1. Final stage

1.2. Chromosomes assemble in sets at both poles

1.3. Small nuclear vesicles begin to re-form

1.4. Nucleus divides

2. ANAPHASE

2.1. 4th stage

2.2. Paired chromosomes (sister chromatids) separated

2.3. Chromosomes begin to move to opposite direction

2.4. Being pulled by spindle fiber

2.5. Parent cell ->two identical daughter cells

2.6. Each pole contains the complete set of chromosomes

3. CYTOKINESIS

3.1. Division of cytoplasm of cell

3.2. Occurs at the end of mitosis & usually in progress before nuclear division complete

3.3. Involves formation of cleavage furrow, pinching the two cell (animal cell)/cell plate (plant cell)

3.4. Cell splits into two after DNA has been replicated & pulled to opposite ends of cell

4. SIGNIFICANCE OF MITOSIS

4.1. Genetic Stability

4.1.1. Maintain same number of chromosomes as parental cells

4.1.2. Daughter cells identical to parent cell

4.1.3. No variation in genetic formation

4.2. Growth

4.3. Cell Replacement

4.3.1. Replacement of cells & tissues

4.4. Regeneration

4.4.1. Starfish

4.4.2. Lizard
