HL Cell Cycle
| Term | Definition |
|---|---|
| 1. Astral microtubules | reach out from chromosomes |
| 2. Benign tumor | not hazardous to health tumor |
| 3. Binary fission | Prokaryotic reproduction (their version of m-phase) |
| 4. Cancer | Uncontrolled replication of cells (caused by damage to DNA) |
| 5. Cell cycle | 2 stages: Interphase & M-phase |
| 6. Cell plate | The plant version of the cleavage furrow |
| 7. Centromere | where spindle fibers attach on the centriol |
| 8. Chromatin | combo protein & DNA |
| 9. Chromosome | package of DNA / genetic info |
| 10. Cleavage furrow | pinching in of animal cell membrane during telophase |
| 11. Cyclin-dependent kinase | protein essential for enzymatic activity |
| 12. Cyclins | subunit of cyclin-dependent kinase |
| 13. Cytokinesis | separation of cytoplasm |
| 14. Histones | structural protein that gets wrapped in DNA to keep (the DNA) organized |
| 15. Interphase | G1 (gap phase) S (synthesis) G2 (growth phase) |
| 16. Karyotype | A person's complete set of chromosomes |
| 17. Kinetochore | what spindle fibers attach to on chromosomes |
| 18. Kinetochore microtubule | Attach to kineticore |
| 19. M phase | Prophase, metaphase, anaphase, telophase |
| 20. Malignant tumor | dangerous to health tumor |
| 21. Metaphase plate | chromosomes line up |
| 22. Metastasis | the spread of cancer cells from the location of first formation to the rest of the body |
| 23. Mitosis | Nuclear replication/division (3/4 of m-phase) |
| 24. Mitotic Index | ratio of cells in mitosis to total cells: Mitotic cells/total cells |
| 25. Motor proteins | "walk along" overlap microtubeules |
| 26. Mutagens | cases genetic mutation(s) (chemical, physical, or biological mutagens) |
| 27. Nucleosome | 8 histones wrapped in DNA |
| 28. Oncogenes | Gene that prompts cell division |
| 29. Overlap microtubules | Pull together or elongate cells |
| 30. Sister chromatids | the duplicated chromosomes, look like X |
| 31. Spindle microtubule fibers | help align/separate sister chromatids (come from centrosomes) |
| 32. Tumor | abnormal tissue mass from cells dividing more & dying less |
| 33. Tumor suppressor genes | helps controll cell growth |
