Answer :
1. Cytokinesis begins during this final stage of mitosis. - Telophase
2. Division of the cytoplasmof the cell. - Cytokinesis
3. Sister chromatids begin to separate. - Anaphase
4. The genetic material of the cell replicates to prepare for cell division. - Interphase
5. Microtubule begin to attach to the centromeres of the sister chromatids - Ptometaphase
6. b. Prometaphase.
In this phase, nuclear membrane breaks down. Kinetochore microtubules invade nuclear space, and attach to kinetochores. Polar microtubulespush against each other, moving centrosomes apart.
7. d. G1 phase check point.
8. e. 1/2
7.
