Mitosis
______3______
2.
Cytoplasm Divides
DO NOW:
How many chromosomes are in each of the four cells
below?
Interphase


Cell duplicates DNA
Individual chromosomes
not yet visible.
The Four phases of Mitosis
PMAT
Prophase





chromatin condenses
(chromosomes are now
visible)
Chromosomes consist of
two sister chromatids
nuclear membrane
disappears
Centrosomes start to
move to opposite ends
(poles) of cell
spindles begin to form
Metaphase



Spindles are fully formed
chromosomes are
attached to spindles at
the centromeres
Chromosomes line up at
the center (equator) of
the cell
Anaphase
• Sister chromatids
separate and move to
opposite poles.
• Each chromatid is now
considered an individual
chromosome
Telophase



2 nuclear envelopes
reform
Chromosomes uncoil
into chromatin
Spindles disappear
Cytokensis

cytoplasm is divided in half
