The Cell Cycle
As eukaryotic cells grow and divide, they pass through a cell cycle that consists of 3 stages:

Stage 2: Cell Division - Mitosis (4 phases)
Phase 1: Prophase
•
DNA compacts into visible form as _________________.
•
Each chromosome contains two strands called _____________________.
•
Sister chromatids are held together by a ________________.
•
The __________ ____________ breaks down
Phase 2: Metaphase

Chromosomes line up in the ___________ of the cell.
Phase 3: Anaphase
•
The centromere splits and sister chromatids ______________.
•
They are now called ____________________________.
•
They move to ________________________________, pulled by
_____________________
Phase 4: Telophase

Final phase of mitosis.
•
Chromosomes _________________and are no longer ____________.
•
A new ________________________ forms around each group of
daughter chromosomes.
Stage 3: Cell Division - Cytokinesis
•
Final stage of cell division.
•
The cytoplasm ____________ and two _______________
cells are formed.
