Cell Cycle
Cell Cycle Mitosis and Cancer
| Question | Answer |
|---|---|
| uncontrolled cell growth ; tumors develop | cancer |
| process of a cell growing and dividing | cell cycle |
| division of the nucleus | mitosis |
| G1 , S and G2 together | Interphase |
| division of the cytoplasm | cytokinesis |
| chromosome splits and sister chromatids pulled to opposite ends of the cell | anaphase |
| chromosomes moved to the middle/equator of the cell | metaphase |
| nuclear envelope dissolves and chromatin condenses into chromosomes | prophase |
| cell almost finished dividing ; chromosomes decondense ; nuclear envelope returns | telophase |
| before S phase can happen ; check for cell growth & if DNA is damaged | G1 checkpoint |
| before mitosis can happen ; check for cell growth & if the DNA was copied | G2 checkpoint |
| before anaphase can happen ; check if spindle attachment is made & attaches to chromosomes | M checkpoint |
| this is made by animals cells towards the end of telophase | cleavage furrow |
| this is made by plant cells towards the end of telophase | cell plate |
| cell growth in the cell cycle | G1 and G2 phase |
| DNA is synthesized or copied | S phase |
| includes mitosis AND cytokinesis | M (mitotic) phase |
| resting phase ; cell is NOT dividing or preparing to divide | G0 phase |
| organelle that produces the spindle fibers in animal cells during mitosis to move chromosomes around | centrioles |
| the product of 1 round of mitosis | 2 identical daughter cells |
| unregulated growth of cells that are noncancerous and do NOT spread | benign tumor |
| unregulated growth of cells that are cancerous, invades and can spread throughout the body | malignant tumor |
| cancer treatments | removal , radiation , chemotherapy |
| possible causes of cancer | too much UV light exposure, tobacco use , genetically inherited, viruses |
| programmed cell death "self-destruct" | apoptosis |
