Interphase
GI - cell grows + produces proteins needed to replicate organelles
S - DNA is replicated
G2 - cell continues to grow.
Prophase
The strands of DNA coil up and condense
centrioles move to the opposite sides and form spindle fibres
nucleolus disappears and the nuclear envelope breaks down.
Metaphase
Chromosomes line up at the cell equator
the centromeres attach to the spindle fibres.
Anaphase
Centromeres divide
sister chromatids separate (the spindle contracts + shorten)
sister chromatids pulled to opposite poles.
Telophase
Chromosomes unravel
new nuclear envelope forms
nucleoli appear.
Cytokinesis
Cytoplasm divides.
