| Mitosis | The process which the nucleus of the cell is divided into 2 nuclei each with some number of chromosomes. |
| Genes | Are segments of DNA. |
| DNA | Stores heredity. Is organized into segments called genes. |
| Chromosome | DNA is made up of. |
| Chromatid | Each of the two threadlike strands into which a chromosome divides during cell division. |
| Centromele | Holds chromatids together until cell division |
| 5 Stages of mitosis | Interphase, Prophase, Metaphase, Anaphase, and Telophase |
| Cytokinesis | The process during cell division in which the cytoplasm divides |
| Prophase | When chromosomes coil up and become visible |
| Metaphase | When the chromosomes move to the center of the cell and line up along the equator. |
| Anaphase | Two chromatids (chromosomes) move toward opposite poles |
| Telophase | A nuclear envelope forms around the chromosomes at each end. Then the chromosomes uncoil. |
| G1 Phase | First growth. Cell grows rapidly and carries out functions |
| S Phase | Synthesis Phase: A cell's DNA is copied |
| G2 Phase | 2nd growth: preparations are made for the nucleus to divide. |
