Place the following events in the order in which they occur during the cell cycle by numbering them from 1. In addition, indicate whether each process occurs during G1,S,G2 prophase, prometaphase, metaphase, anaphase, telophase, or cytokinesis. For the purposes of this question, assume the cell cycle starts with the beginning of interphase. _____ Spindle poles separate and move toward cell periphery _____ Cell growth (after DNA replication) _____ Nuclear envelope breakdown _____ Cleavage furrow formation _____ Sister chromatids move towards spindle poles _____ Alignment of chromosome along cell equator _____ Interpolar microtubule interactions begin _____ Complete chromosome decondensation _____ Nuclear lamin dephosphorylation _____ DNA replication _____ Kinetochore microtubule attachment to chromosomes _____ Sister chromatid condensation _____ Beginning of contractile ring assembly _____ Nuclear envelope reassembly _____ Centrosome duplication _____ Suspension of cell cycle until all chromosomes attach to mitotic spindle _____ Astral microtubule nucleation _____ Sister chromatid separation _____ Complete separation of one cell into two new daughter cells

5. Astral microtubule nucleation (Prophase)
6. Kinetochore microtubule attachment to chromosomes (Prometaphase)
7. Alignment of chromosome along cell equator (Metaphase)
8. Sister chromatids move towards spindle poles (Anaphase)
9. Complete chromosome decondensation (Telophase)
10. Nuclear envelope reassembly (Telophase)
11. Nuclear lamin dephosphorylation (Telophase)
12. Beginning of contractile ring assembly (Cytokinesis)
13. Cleavage furrow formation (Cytokinesis)
14. Complete separation of one cell into two new daughter cells (Cytokinesis)
15. Suspension of cell cycle until all chromosomes attach to mitotic spindle (Metaphase)
16. Interpolar microtubule interactions begin (Metaphase)
17. Cell growth (after DNA replication) (G2)
18. Spindle poles separate and move toward cell periphery (Prophase)
