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 |
