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
