Across 4. Phase of mitosis- preparation for sister chromatid separation 10. Two of these are inside of the centrosomes 11. Characteristic chromosome number 13. Producing human tissue 16. Main microtubule-organizing center of the cell 17. Phase of mitosis- gives rise to two daughter cells 18. Sister chromatids are attached here 19. Spindle disappears as nuclear envelope forms

Down 1. Indentation of nuclei between two daughter nuclei 2. Cloning an individual 3. Array of microtubules 5. Half of the diploid number 6. Protein complexes developed on either side of centromeres 7. DNA is located here 8. Indicates future axis of cell division 9. Newly formed plasma membrane 12. Proteins involved in organizing chromosomes 14. Phase of mitosis- nuclear division is about to occur 15. Phase of mitosis- centromeres of chromosomes are aligned
