rosaleah-cell cycle
| Term | Definition |
|---|---|
| cell cycle | Sequence of events from the production of a eukaryotic cell to the time the cell itself reproduces. |
| Mitosis | Process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed, forming two daughter nuclei. |
| Interphase | Stage of the cell cycle during which a cell carries out its metabolic processes and performs its function in the body. |
| Cytokinesis | Process by which the cytoplasm of a cell is divided in two; usually follows mitosis and meiosis. |
| Prophase | First stage of mitosis and of meiosis 1 and 2, when the already replicate chromosomes condense. |
| Metaphase | Second stage of mitosis and of meiosis 1 and 2 when the spindle is fully formed and all of the chromosomes are held in place. |
| Anaphase | Third phase of mitosis and of meiosis 1 and 2, in which the sister chromatids separate and move toward the poles of the spindle. |
| Telophase | Final stage of mitosis and of meiosis 1 and 2, in which the chromosomes reach the spindle poles, nuclear envelopes form around each set of daughter chromosomes, and the nucleoli reappear. |
| Daughter cell | |
| Cancer | Disease caused by severe disruption of the mechanisms that normally control the cell cycle. |
| Reproduction | |
| Chromatin | Combination of DNA and protein molecules, in the form of long, thin fibers, making up the genetic material in the nucleus of a eukaryotic cell. |
| Chromatids | |
| Centromere | Region where two sister chromatids are joined tightly together. |
| Chromosome | Condensed threads of genetic material formed from chromatin as a cell prepares to divide. |
| Spindle | Framework of microtubules that guide the movement of chromosomes during mitosis and meiosis. |
