Across
- 9. the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
- 11. leading them to stop growing when the density of cells reaches a certain point
- 14. threadlike structures made of protein and a single molecule of DNA
- 16. cancerous and can spread cancer cells throughout one's body through the blood or lymphatic system
- 17. the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases
- 19. signaling at cell division is largely dedicated to completing a decision made in G1 phase—to initiate and complete a round of mitotic cell division
- 20. the third subphase of interphase in the cell cycle directly preceding mitosis
- 21. the complete set of genetic information in an organism
- 24. a series of events that takes place in a cell as it grows and divides
- 26. a protein structure that divides the genetic material in a cell
Down
- 1. the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells
- 2. protein kinases characterized by needing a separate subunit - a cyclin - that provides domains essential for enzymatic activity
- 3. the region where the cell's spindle fibers attach
- 4. the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell
- 5. the cyclin-Cdk complex that was discovered first in frog eggs
- 6. the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
- 7. cyclin-dependent kinase activity promotes DNA replication and initiates G1-to-S phase transition
- 8. an organism's reproductive cells.
- 10. a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells
- 12. the cells in the body other than sperm and egg cells
- 13. the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
- 15. a cellular structure involved in the process of cell division
- 18. one of the two identical halves of a chromosome that has been replicated in preparation for cell division
- 22. the regulatory subunits of kinases that control progress through the cell cycle
- 23. surveillance mechanisms that monitor the order, integrity, and fidelity of the major events of the cell cycle
- 25. the presence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair
