Cell division: Mitosis…

stages:
 Interphase
 Mitosis
 Cytokinesis
 Cell
cycle- the regular sequence of
growth and division that cells undergo.
Stage 1:Interphase… (prepstage)
 Grow
 DNA
 Prepares
to divide

 Duplicated
chromosomes to the middle.
 Sister chromatids on either side.

Cell Cycle…
What it does…
mitosis
Interphase
Cytokinesis
o Grow
o DNA replicates (exact cop)
o Prepares to divide
Prophase
o Nuclear membrane and nucleolus
disappear.
o Spindle fibers appear
o See duplicated chromosomes.
Metaphase
o Duplicated chromosomes move to the
middle
o Sister chromatids on either side
Anaphase
o Sister chromatids separate and move to
opposite ends
Telophase
o Nuclear membrane and nucleolus reappear
o Chromosomes loosen up and become
chromatin
o Always moving to the next stage
