| cell cycle | the regular sequence of growth and division that cells undergo |
| interphase | the stage of the cell cycle that takes place before cell division occurs; during this stage, the cell grows, copies its DNA, and prepares to divide |
| replication | the process by which a cell makes a copy of the DNA in its nucleus |
| mitosis | the stage of the cell cycle during which the cell's nucleus divides into two new nuclei and one copy of the DNA is distributed into each daughter cell |
| chromosome | a doubled rod of condensed chromatin; contains DNA that carries genetic information |
| chemotherapy | the use of drugs to kill cancer cells |
| cytokinesis | the final stage of the cell cycle, in which the cell's cytoplasm divides, distributing the organelles into each of the two new cells |
| cancer | a disease in which some body cells grow and divide uncontrollably, damaging the parts of the body around them |
| mutation | a change in a gene or chromosome |
| tumor | a mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably |
