| Term | Definition |
|---|
| cell cycle | the regular sequence of growth and division that cells undergo |
| interphase | the overall period of growth in a cell's life; spends the most time here |
| mitosis | the overall period of division in a cell's life |
| prophase | 1st phase of mitosis; chromosomes are visible; nucleus breaks down; spindles start to form |
| metaphase | chromosomes move to the middle of the cell; spindles are attached to centromeres |
| anaphase | centromeres split and sister chromatids are pulled to opposite ends of the cell |
| telophase | final phase of mitosis; nucleus reforms; chromosomes uncoil; cell plate forms in plant cells |
| cytokinesis | dividing of the cytoplasm that occurs after telophase to form daughter cells |
| G0 | non-dividing, "resting" stage of interphase |
| G1 | active time cell (growth, protein production, metabolism) |
| S | time for DNA replication |
| G2 | final prep for cell division; chromatin begin to coil |
| chromosome | condensed, coiled DNA |
| chromatin | uncoiled DNA |
| sister chromatids | two strands of genetically identical chromosomes that are attached by a centromere |
| centrioles | two small structures that move to opposite ends of the animal cell; help with spindle fibers |
| centromere | structure that keeps the two sister chromatids attached |
| spindle fibers | strands that pull sister chromatids (act like "puppet-strings") |
| cell plate | eventually becomes a cell wall; seen in telophase in plant cells |
| replication | copying of DNA |
| cancer | a group of diseases that involve abnormal, uncontrolled growth and division of cells |
| carcinogen | a cancer-causing substance |
| tumor | a mass of abnormal cells that develop when cancer cells divide and grow uncontrollably |
| benign | not usually dangerous to health |
| malignant | dangerous to health; referring to an abnormal growth that tends to spread |
| metastasize | spread of a cancer(malignant) to distant tissues |
