Mitosis
| Term | Definition |
|---|---|
| Mitosis | cell division |
| Chromosome | tightly coiled DNA (easy to move) |
| Chromatin | loosely coiled DNA (easy to read) |
| Chromatid | chromosomes after they split |
| Centriole | DNA "fishing pole" (used to move DNA) |
| Spindle Fiber | DNA "fishing line" (used to move DNA) |
| Centromere | holds sister chromatids together |
| Nucleus | contains DNA |
| Sister Chromatids | identical pieces of chromosome |
| Parent Cell | the original cell |
| Daughter Cells | the "offspring" of a parent cell |
| DNA | instructions for a cell's life |
| Genes | pieces of DNA that code for traits |
| Interphase | G1 S and G2 phases of the cell cycle |
| Prophase | the beginning of mitosis; chromosomes, spindle fibers, and centrioles form; nucleus dissolves |
| Metaphase | chromosomes line up in the middle of the cell; spindle fibers attach at centromeres |
| Anaphase | spindle fibers shorten and chromosomes are pulled to each pole |
| Telophase | centrioles and spindle fibers dissolve; a new nucleus forms |
| Cytokinesis | cell splits into two fully independent cells |
