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.
