- Mitosis
- Prometaphase
- kinetochores assemble at centromeres and attach at kinetochores to connect centromere to centrioles
- Telophase
- chromosomes decondense, spindle fibres disperse
- Prophase
- chromosome condense, nuclear envelope disappears
- centrosomes move to opposite sides of cell, spindle forms
- Cytokinesis
- Animals
- constriction belt of actin microfilament around equator of cell, cleavage furrow forms, splits cell in two
- Plants
- formation of new cell wall/cell plate, DNA becomes non-visable back to chromatin
- Animals
- Metaphase
- chromosomes lined up an equator of spindle, centrosomes at opposite ends of cell
- Anaphase
- centromeres separate, chromosomes pulled to opposite poles of cell by spindle fibres
- Interphase
- G1 period
- 90% of cell life spent here, cell performs normal functions
- S period
- DNA is duplicated, centrosome duplicates itself
- G2 period
- cell prepares to divide, chromosomes not visible
- G1 period
- Prometaphase
