| Question | Answer |
|---|---|
| Cell Cycle | the life cycle of a cell. this includes both interphase and mitosis/cytokinesis. interphase is broken into G1, S, and G2 |
| Sister Chromatids | identical copies of a chromosome. one goes to each daughter cell during cell division |
| mitosis | division of the nucleus in a eukaryote |
| cytokinesis | division of the cell's cytoplasm to produce two daughters |
| centromere | region that joins the two sister chromatids before their separation |
| kinetochore | region on chromatid to which the spindle microtubule attaches |
| spindle | network of microtubules that extend from the poles of the dividing cell to each chromatid. these microtubules shorten and help to pull the chromatids apart during anaphase. |
| clevage furrow | the infolding in the cell membrane produced by the contractile ring. |
| contractile ring | this ring (made of protein actin - one component of the cytoskeleton) forms around the midline of an animal cell following mitosis. the ring contracts, pinching the cell's membrane inward, thus initiating cytokinesis. |
| cell plate | the new cell wall that forms during the cytokinesis of plant cells. this develops into a full cell wall that separates the daughter cells. |
