Mitosis & Meiosis

Steps of Mitosis:

1. DNA is found as chromosomes in the nucleus

2. Chromosomes become visible as each chromosome is copied & joined together

3. Nuclear membrane disappears and chromosomes line up along the centre of the cell

4. Chromosomes are pulled apart to opposite poles by contracting fibres

5. Nuclear membrane forms around each group of chromosomes & the cytoplasm divides

6. Two new genetically identical daughter cells are formed

Steps of Meiosis:

1. Chromosomes make identical copies of themselves

2. The cell divides twice to form four gametes, each with a single set of chromosomes

3. All gametes are genetically different from each other
