1. The Cell Cycle

2. The Life of a Cell
Cells pass through different __________ in their lives
These stages = __________
Begins when cell forms, and ends when cell divides
Before division, has to copy its ______

3. Prokaryotic or Eukaryotic?
Prokaryotic cells: simple! No membrane covered organelles, small circle of DNA.
Split into 2 parts = ________________
Each new cells contains 1 copy of the DNA

4. Eukaryotic cells More ___________; more DNA
DNA is in chromosome pairs = _____________ chromosomes
Humans have 23 pairs, or 46 total

5. What do chromosome pairs look like?

6. The Cell Cycle

7. Phases of the Cell Cycle
IPMAT
Interphase: Cell _______ (G1 and G2), and copies its DNA (S = synthesis)

8. A Cell’s Life
Interphase
Mitosis
Prophase
Metaphase
Anaphase
Telophase

9. Phases of Mitosis
Prophase: PREPARATION phase; DNA twists into _____________, nuclear membrane breaks down
Metaphase: Chromosomes MEET in the ____________ of the cell
Anaphase: Chromosomes ___________ and move APART
Telophase: The cell ______ into two

10. Prophase
Chromosomes starting to form, nuclear ______________ starts to break apart

11. Metaphase
Hint: Think of this as the meta or (middle) phase where chromosomes line up in the middle of the cell.

12. Anaphase
Hint: This is were the 2 sisters Ana and Ana are pulled apart to different ends of the cell…so sad.

13. Telophase
Hint: Now the sisters are far apart and starting separate lives. They have to call each other by TELOphone.

14. Cytokinesis
At the end of Telophase the cell membrane _____________ into two identical cells.
Animal Cell
Plant Cell
In plant cells a cell plate forms and later becomes the cell membrane.

15. QUIZ The cell cycle is the cell’s what?
What two main stages make up the cell cycle?
What happens during Interphase?
Mitosis is all about a cell doing what?

16. QUIZ CONT.
In what phase of Mitosis do the chromosomes line up in the center of the cell?
In what phase of Mitosis do the spindle fibers first pull the chromosomes apart?
In what phase of the Mitosis do chromosomes start to form?
