1. Cell Cycle Practice Quiz

2. Draw an overview of the cell cycle.

3. Answer

4. What is the longest stage of the cell cycle?

5. Interphase
answer

6. What is the longest stage of interphase?

7. G1
answer

8. What happens in the G1 Phase?

9. Growth
Prepares to copy DNA
answer

10. What happens in the S phase?

11. answer S stands for Synthesis DNA is copied
Humans have 46 chromosomes it is doubled to 92 during the S phase
answer

12. What happens in G2 phase?

13. Grows
Duplicates organelles and makes proteins necessary for splitting the cell.
answer

14. Describe the M Phase of the cell cycle.

15. answer M stands for mitosis, M phase is made up of four parts:
Prophase
Metaphase
Anaphase
Telophase
answer

16. Describe prophase

17. answer Chromatin condenses into chromosomes The nucleus disappears
The centrioles move to the sides of the cell.
The spindle (microtubules) form and grab onto the DNA.
answer

18. What happens in metaphase?

19. Once the microtubules pull the chromosomes to the middle it is in metaphase
answer

20. What happens in anaphase?

21. The chromosomes get pulled to opposite sides of the cell.
Answer

22. Describe telophase

23. answer Chromosomes are pulled to opposite sides. The nucleus reforms
The cell starts to split
In animals the split is called a cleavage furrow
In plants the split is called a cell plate
answer

24. Just be aware the cytokinesis is the act of splitting one cell into two cells.

25. Draw a cell in each phase.

26. answer
