Describe the stages of the cell cycle. In your description of mitosis, list the four parts in the correct order.

Mitosis has 4 main parts:

1) Prophase - Chromosomes become visible, spindle fibres form, nuclear envelope dissolves.

2) Metaphase - Chromosomes line up in the middle of the cell.

3) Anaphase - Chromosome pairs separate to different sides of the cell by the spindle fibres.

4) Telophase - New nuclei are formed around each grouping of Chromosomes.

Cytokinesis then splits the cytoplasm into 2, forming 2 new daughter cells.

G1 phase - period of growth and activity. Also, the time where the cell performs its function (ex. liver cells producing insulin)

S phase - synthesis - stage where DNA replication occurs

G2 phase - continued growth, building of spindle fibres and centrioles, both structures needed for Mitosis phase.
