Interphase• grow• DNA replicates (exact copy)• prepares to divide

Prophase• nuclear membrane and nucleus disappear• spindle fibers appear(ropes)• see duplicate chromosomes

Anaphase• sister chromatids separates and move to oppositeends

Metaphase• duplicated chromosomes move to the middle• sister chromatids on either side

CELL CYCLEInterphase
-grow-DNA replicates (exact copy)-prepares to divide
MITOSIS
Prophase-nuclear membrane and nucleus disappear-spindle fibers appear (ropes)-see duplicated chromosomes
Metaphase
-duplicated chromosomes move to the middle-sister chromatids on either side.
Anaphase
-sister chromatids separates and move to opposite ends
Telophase
-nuclear membrane and nucleolus reappear-chromosomes loosen up and become chromatin.
Cytokinesis
-Always moving to the next stage.
