| Chromatin | Loosely packed DNA |
| Chromosome | Tightly packed DNA |
| Chromatid | One of two identical "sister" parts of a replicated chromosome |
| Homologous Chromosome | A term used to refer to a chromosomes that have the same genes in the same locations but different versions of those genes. |
| Diploid | A cell that has two copies of each type of chromosome |
| Binary Fission | The way a bacteria (prokaryotic cell) reproduces |
| Interphase | A stage of the cell cycle when the cell is growing and copying it's DNA |
| Gap 1 (G1) | The first step in interphase, cell growth is occuring |
| S-phase | The second stage of Interphase, DNA replication is occuring |
| Gap 2 (G2) | The third stage of interphase, cell growth is occuring |
| Mitotic Phase | A stage of the cell cycle when the cell (both the cytoplasm and nucleus) is actively dividing |
| Mitosis | The division of the nucleus |
| Prophase | The first step of Mitosis, the DNA is condensing into visible chromosomes |
| Metaphase | The second step of Mitosis, the chromosomes line up down the center of the cell |
| Anaphase | The third step of Mitosis the sister chromatids seperate and move to opposite sides of the cell |
| Telophase | the last step of Mitosis, two nuclei are beginning to re-form |
| Cytokinesis | The division of the cytoplasm |
| Cleavage furrow | The indentation that forms to split animal cells into 2 |
| Cell plate | The cell wall that forms to divide 2 plant cells |
