| Cell division | process by which a cell divides into two new daughter cells |
| Chromatid | one of two identical "sister" parts of a duplicated chromosome |
| Centromere | area where the chromatids of a chromosome are attached |
| Interphase | period of the cell cycle between cell divisions |
| Cell cycle | series of events that cells go through as they grow and divide |
| Mitosis | part of a uekayote cell division during which the cell nucleus divides |
| Prophase | first and longest phase off mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus |
| Centriole | one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope |
| Spindle | fanlike microtubule structure that helps separate the chromosomes during mitosis |
| Metaphase | second phase of mitosis, during which the chromosomes line up across the center of the cell |
| Anaphase | the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles |
| Telophase | fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material |
| Cytokinesis | division of cytoplasm during cell division |
| Cyclin | one of a family of closely related proteins that regulate the cell cycle in eukaryote cells |
| Cancer | disorder in which some of the body's own cells lose the ability to control growth |
