Across
- 3. condition marked by the presence of a double complement of genetic material (two sets of chromosomes, one set inherited from each of two parents)
- 6. final stage in cell division, where the cytoplasm divides to form two separate daughter cells
- 7. network of microtubules, originating from centrioles, that arranges and pulls apart chromosomes during mitosis
- 9. all cells of the body excluding gamete cells
- 10. one of a group of enzymes associated with cyclins that help them perform their functions
- 13. region of a centromere where microtubules attach to a pair of sister chromatids
- 14. describes two copies of the same chromosome (not identical), one inherited from each parent
- 15. third phase of the cell cycle, after the DNA synthesis phase
- 17. contractile ring that forms around a cell during cytokinesis that pinches the cell into two halves
- 18. stage of the cell cycle during which DNA replication occurs
- 21. linear alignment of sister chromatids in the center of the cell, which takes place during metaphase
- 22. second stage of mitosis (and meiosis), characterized by the linear alignment of sister chromatids in the center of the cell
- 23. progress point in the cell cycle during which certain conditions must be met in order for the cell to proceed to a subsequence phase
- 24. first stage of mitosis (and meiosis), characterized by breakdown of the nuclear envelope and condensing of the chromatin to form chromosomes
- 25. cellular structure that organizes microtubules during cell division
- 26. entire life cycle of a cell, excluding mitosis
Down
- 1. one of a group of proteins that function in the progression of the cell cycle
- 2. phase of the cell cycle, usually entered from the G1 phase; characterized by long or permanent periods where the cell does not move forward into the DNA synthesis phase
- 4. phase of the cell cycle in which a cell undergoes mitosis
- 5. life cycle of a single cell, from its birth until its division into two new daughter cells
- 8. one of a pair of identical chromosomes, formed during DNA replication
- 11. first phase of the cell cycle, after a new cell is born
- 12. division of genetic material, during which the cell nucleus breaks down and two new, fully functional, nuclei are formed
- 16. third stage of mitosis (and meiosis), during which sister chromatids separate into two new nuclear regions of a dividing cell
- 19. region of attachment for two sister chromatids
- 20. final stage of mitosis (and meiosis), preceding cytokinesis, characterized by the formation of two new daughter nuclei
