1. What term describes DNA in G1 phase? Chromatin

2. What happens to the DNA in S Phase? What is DNA called? Doubled, duplicated, copied Chromatin

3. What happens to DNA in G2? What is DNA called at the end of this phase? DNA is coiled, condensed, and joined to its duplicate Duplicated chromosome Label the centromere. Label the sister chromatids

4. What happens to centrioles and everything else in the cytoplasm during G2 phase? Centrioles double Everything doubles

5. How would you describe sister chromatids? Joined, identical chromosomes

6. What is the first phase of mitosis? prophase

7. What happens to the nuclear envelope during prophase? dissolves

8. What is produced from the centrioles during prophase? Spindle Fibers

9. Where do spindle fibers attach to chromosomes? centromere

10. What happens by the end of prophase? Centrioles have moved to opposite poles Spindle fibers have attached to the centromere of the duplicated chromosomes

11. Name the second phase of mitosis. Metaphase What does “meta” mean? middle

12. Where do chromosomes align themselves during metaphase? At the equator

13. Name the third phase of mitosis. Anaphase What does “ana” mean? To separate

14. What marks the beginning of anaphase? Spindle fibers begin to separate duplicated chromosomes (sister chromatids)

15. What do we call the DNA being pulled towards the poles? Unduplicated chromosomes

16. Name the fourth phase of mitosis. Telophase What does “telo” mean? The end

17. What marks the beginning of telophase? Unduplicated chromosomes have reached the poles

18. What happens to chromosomes during telophase? Contained inside the nuclear membrane

19. What happens to spindle during telphase? Break down

20. What happens to the nuclear envelope during telophase? Two new nuclear envelopes form

21. How many nuclei are produced after mitosis? How many cells? 2 nuclei 1 cell

22. What happens during cytokinesis? Everything outside the nucleus in the cytoplasm split into two separate cells
