Unit 6 Notes: The Cell Cycle

2. (1) Big Ideas: Cells spend most of their “life” preparing to divide.
Cells prepare for division because:
Need to Grow
Need to Copy DNA
Need to Check for Errors

3. (2) The Cell Cycle Interphase: Cell Division (M-Phase): G1 Phase
S Phase
G2 Phase
Cell Division (M-Phase):
Mitosis  If a Non-Sex Cell
Meiosis  If a Sex Cell

5. (3) G1 Phase 1st Growth Phase: G1 CheckPoint: Cell Increases in Size.
Extra Proteins & Organelles are made.
G1 CheckPoint:
After G1 Phase
Makes sure enzymes are ready for DNA Replication.
Makes sure extra proteins and organelles are made.

7. (4) S Phase Synthesis Phase: Exact copy of cell’s DNA is made:
Extra DNA is Synthesized.
DNA is Replicated or Copied.
Exact copy of cell’s DNA is made:
Mistakes  Termination or Cancer.
DNA copied inside nucleus.

9. (5) G2 Phase 2nd Growth Phase: G2 CheckPoint: Cell Grows More.
Remaining Proteins & Organelles Made.
G2 CheckPoint:
After S and G2 Phase.
Makes sure DNA was replicated correctly.
Makes sure all proteins and organelles were copied.

11. (6) M Phase (Cell Division):
Mitosis OR
Meiosis
