| This is the period of time between cell divisions | Interphase |
| If a cell with 18 chromosomes during G1 divides by mitosis, each offspring will have how many chromosomes | 18 |
| DNA is replicated during this phase | S |
| If a cell has double the # of chromosomes but has not yet divided it is in this phase | G2 |
| These proteins help to organize DNA into chromosomes | Histones |
| Spindle fibers are made up of these | Microtubules |
| This is the phase where the sister chromatids separate | Anaphase |
| In this phase the chromatin condenses to form chromosomes | Prophase |
| In this phase the chromosomes line up along the equator of the cell | Metaphase |
| In this phase a cell plate is being formed | Telophase |
| This is the phase that an adult cell that rarely divides is in. | G0 |
| The division of the whole cell is called | Cytokinesis |
| The sequence of growth and division of a cell is called the | Cell cycle |
| This is the phase in which one could observe what the chromosomes are doing | M |
| Cyclins work by activating | Kinases |
| These monitor the cell's DNA for damage, the condition of the chromosomes and the spindle. | Checkpoints |
| These cells pinch in during telophase. | Animal |
| These cells form a cell plate during telophase. | Plant |
| This is the form the DNA takes on during Interphase. | Chromatin |
| This is a disease in which abnormal cells develop, multiply and invade normal tissues | Cancer |
| A gene that , if mutated, can cause normal cells to become cancerous | proto-oncogene |
| Each strand of a couble-stranded chromosome is known as a | sister chromatid |
| Checkpoints | monitor and control the cell cycle |
| Tumor suppressors | produce checkpoint proteins that help inhibit cell division |
| Once cancer cells enter the blood stream, they are able to move to other parts of the body and form new tumors in a process known as | metastasis |
| The surface area of a cell increases at a ___ rate than the volume | slower |
| Angiogenesis | Means new blood vessel growth |
