| Centromere | A structure that connects two identical chromatids |
| Chromatin | Genetic material inside the nucleus that is not condensed or packaged |
| Cytokinesis | The final stage of the cell cycle where the cell membrane pinches to form two daughter cells |
| The Cell Cycle | The regular sequence of growth and division of a cell |
| Chromosome | Condensed chromatin that contains genetic material |
| Chromatid | One of an identical rods of chromosome |
| Interphase | The time a cell spends preparing for division |
| Cell Growth | The cell doubles its size, copies its structures, matures, and produces proteins |
| DNA Replication | The cell makes an exact copy of its DNA |
| Preparation for Division | The cell checks for errors and makes corrections |
| Mitosis | Cellular division |
| Prophase | The nuclear membrane breaks down and chromatin condenses to form chromosomes; spindle fibers appear |
| Metaphase | Chromosomes line up along the center of the cell |
| Anaphase | Chromosomes split at their centromeres and move to opposite ends of the cell |
| Telophase | The cell is about to split; 2 new nuclei appear |
| Karyotype | A display of human chromosomes arranged in pairs |
| Trisomy 21 | Down's Syndrome |
