| The point on a chromosome which is attached to a spindle fiber during cell division. | Centromere |
| The material by which the chromosomes of organisms other than bacteria are composed of. (They are also made up of DNA and RNA). | Chromatin |
| The two copies of a chromosome after it has been replicated. | Sister Chromatid |
| The stage in which the cell increases in size during each division. | Interphase |
| The first (and longest) stage of mitosis in which the chromosomes become visible and the nuclear envelope disappears. | Prophase |
| The second phase of mitosis in which the chromosomes become attached to the spindle fibers. | Metaphase |
| The third stage of mitosis in which the chromosomes move away from one another to opposite sides of the spindle. | Anaphase |
| The fourth and last process of mitosis in which the chromosomes move to opposite ends of the cell, and two nuclei are formed. | Telophase |
