7821108685 | G1 Phase | First stage of interphase in which cell grows and performs its normal functions. Cell is diploid. | 0 | |
7821108686 | G0 Phase | Cell is performing its normal functions, but has left the cell cycle and is not dividing. | 1 | |
7821108687 | S Phase | The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated. | 2 | |
7821108688 | G2 Phase | Last stage of interphase in which cell grows and performs its normal functions. Cell is tetraploid. | 3 | |
7821108689 | Interphase | Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases | ![]() | 4 |
7821108690 | Prophase | Phase of mitosis in which chromosomes condense, nuclear membrane disappears, nucleolus disappears, and spindle fibers begin to form. | ![]() | 5 |
7821108691 | Metaphase | Phase of mitosis in which spindle fibers help chromosomes line up on the midline of the cell. | ![]() | 6 |
7821108692 | Anaphase | Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell. | ![]() | 7 |
7821108693 | Telophase | Phase of mitosis during which chromosomes uncoil, a nuclear envelope returns around the chromatin, and a nucleolus becomes visible in each daughter cell" | ![]() | 8 |
7821108694 | Cytokinesis | At the end of telophase, actin fibers form an equator around the cell and contract, separating the cytoplasm into two daughter cells. | ![]() | 9 |
7821108695 | Centriole | A paired cluster of microtubules near the nucleus in animal cells. This organelle organizes spindle fibers during mitosis. | 10 | |
7821108696 | Centromere | Region of a chromosome where the two sister chromatids attach to one another. Contains the kinetochore. | 11 | |
7821108697 | Kinetochore | A specialized region on the centromere that links each sister chromatid to the mitotic spindle. | 12 | |
7821108698 | Spindle Fibers | Made of microtubules that connect centrioles to kinetochores of chromosomes and that separate sister (mitosis) or homologous (meiosis) chromosomes during cell division | 13 | |
7821108699 | Chromosome | A threadlike, gene-carrying structure found in the nucleus. Each chromosome consists of one very long DNA molecule and associated proteins. | 14 | |
7821108700 | Chromatid | One of two identical "sister" parts of a duplicated chromosome. | 15 | |
7821108705 | Cyclin-Dependent Kinase (CDK) | A group of protein kinases that are activated by the formation of a complex with a cyclin and are involved in the regulation of the cell cycle. Only active when bound to a cyclin. | 16 | |
7821108706 | Cyclin | A cellular protein that occurs in a cyclically fluctuating concentration and that plays an important role in regulating the cell cycle. | 17 | |
7821108712 | Kinase | An enzyme that adds a phosphate group to a protein. Phosphorylation usually activates protein activity. | 18 | |
7821108713 | Phosphatase | An enzyme that removes a phosphate group from a protein. Phosphorylation usually activates protein activity. | 19 | |
7821405924 | metastasis | the spread of cancer cells distant from the original site | 20 |
