| A | B |
|---|
| prophase | chromosomes are visible, nucleus is not |
| metaphase | chromosomes move to the middle |
| anaphase | chromatids separate/move to sides |
| telophase | two new nuclei |
| cytokinesis | cell division |
| G1 (Gap1) | cell growth and rest |
| G2 (Gap2) | second cell growth/rest phase |
| S phase | DNA is duplicated |
| Interphase | G1,S, G2 |
| Checkpoints | Cell stops to see if all is ready for next phase |
| G1/S checkpoint | Is cell ready for DNA synthesis? |
| G2/M Checkpoint | Did DNA copy correctly? |
| M checkpoint | Is cell ready to complete Mitosis and divide? |
| Centromere | The tie around the middle of 2 chromatids |
| Centrosome | Holds the Centrioles |
| Centrioles | Makes the Spindle fibers |
| Spindle Fibers | Guides the chromatids to the poles. |
| Cell plate | Only in plant cells that are dividing |
| Histone | Protein in the Chromatin--holds DNA coils |
| Chromatin | DNA and Histones. |
