Mitosis
lasts about 1 hour.
-
Prophase
– nuclear envelope breaks down; the internal cell organization is
replaced by the spindle; chromatin becomes densely packed and chromosomes
appear
-
Metaphase
– chromosomes arrange equatorially; the fibers of the spindle attach
to the centomeres
-
Anaphase
– chromosomes are moved to the different poles by shortening
the fibres
-
Telophase
– nuclear envelope is reassembled; chromosomes unravel (became chromatin
again)
-
Cytokinesis
– division of cytoplasm, two cells separate
