1. Cell division Review

2. This spot that holds the 2 chromatid copies together is called a ________________ centromere The phase of the cell cycle in which cells stop dividing all together. G0G0

3. Cell division in bacteria cells is called _______________________ Binary fission Phase of the cell cycle in which DNA is copied S (synthesis)

4. The proteins that control the cell cycle cyclins Phase of the cell cycle in which the nuclear membrane is present and DNA is spread out into chromatin. interphase

5. Type of cell division in eukaryotic cells that results in 2 identical daughter cells. mitosis List the phases of mitosis in order starting with prophase. Prophase, metaphase, anaphase, telophase, cytokinesis

6. Phase of mitosis that follows anaphase telophase Phase of the cell cycle that follows G 2 Mitosis (prophase)

7. This network of fibers that attach and pull the chromosomes apart is called the mitotic ______________ spindle This cell is in __________________ prophase

8. G 1, S, and G 2 make up this phase of the cell cycle. interphase Area near the nucleus that contains the centrioles and helps to organize spindle formation ______________ centrosome

9. The place in the cell membrane of an animal cell that pinches in during cytokinesis is called a ____________________ cleavage furrow Plant cells can’t pinch to divide, instead they form a _______________ to divide. cell plate

10. This phase of the cell cycle is ______________ anaphase Part of interphase in which the cell grows to mature size and carries out its job. G1G1

11. Phase of mitosis that follows prophase metaphase Phase of the cell cycle that follows S G2G2

12. This phase of the cell cycle is ________________ metaphase Phase of the cell cycle cell’s spend most of their time in. G 1 of interphase

13. Disorder in which body cells lose their ability to control cell division cancer One of 2 identical arms that make up a chromosome chromatid

14. DNA that is all spread out in an interphase nucleus is called ________________ chromatin Phase of mitosis in which the nuclear membrane and nucleolus disappear and the DNA scrunches into chromosomes. prophase

15. In this part of interphase cells make the molecules and organelles needed for cell division G2G2 The 2 copies of each chromosome are called ______________ chromosomes because are the same size, same shape, and carry genes for the same traits. homologous

16. These structures at the poles which attach to the spindle fibers and pull the chromosomes. centrioles The cell above is in ______phase meta

17. When chromatin scrunches together it is called a _________________ chromosome One of 2 identical arms that make up a chromosome chromatid

18. Phase of mitosis that follows metaphase anaphase Phase of the cell cycle that follows G 1 S

19. This cell is in ___________ anaphase Phase of cell division in which the nuclear membrane returns and chromosomes spread out into chromatin. telophase

20. This cell is in cytokinesis The cell above is a _________ cell. animal plant Plant You can see the cell plate forming in center instead of a cleavage furrow.

21. Substance that causes cancer carcinogen Phase of the cell cycle after S phase in which cells make the molecules and organelles needed for cell division G2G2

22. Phase of mitosis in which chromatids separate and move to opposite ends of the cell. anaphase The very first dividing phase is _______________ prophase

23. Phase of the cell cycle where cells spend most of their time. They grow bigger and they do their job as body cells. G1G1 List the phases of mitosis in order starting with interphase Interphase, prophase, metaphase, anaphase, telophase, cytokinesis

24. This is called a ______________ Cleavage furrow This cell is _____________ cell. an animal a plant an animal Plants don’t have cleavage furrows.

25. Condition in which a cell grows too big for its DNA to handle the demand for information DNA overload

26. Phase of mitosis where the cytoplasm splits into 2 CYTOKINESIS Name the phases of the cell cycle in order starting with G 1 G 1 S G 2 M C
