Mitosis

Question 1

Question 2

What happens when a diploid cell divides by mitosis?

Answer 2

You get 2 cells that are both diploid

Question 3

5 steps of mitosis

Answer 3

1) Cell duplicates DNA so there’s one copy for each cell.
2) Chromosomes then line up at the centre of the cell and cell fibres pull them apart.
3) The 2 arms of each chromosome go to opposite ends of the cell.
4) Membranes form around the new set of chromosomes. These become the nuclei of the 2 new cells.
5) Lastly, the cytoplasm divides.
