| 9767854573 | G1 Phase | First stage of interphase in which cell grows and performs its normal functions. Cell is diploid. | 0 | |
| 9767854574 | G0 Phase | Cell is performing its normal functions, but has left the cell cycle and is not dividing. | 1 | |
| 9767854575 | S Phase | The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated. | 2 | |
| 9767854576 | G2 Phase | Last stage of interphase in which cell grows and performs its normal functions. Cell is diploid. | 3 | |
| 9767854577 | Interphase | Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases |  | 4 |
| 9767854578 | Prophase | Phase of mitosis in which chromosomes condense, nuclear membrane disappears, nucleolus disappears, and spindle fibers begin to form. |  | 5 |
| 9767854579 | Metaphase | Phase of mitosis in which spindle fibers help chromosomes line up on the midline of the cell. |  | 6 |
| 9767854580 | Anaphase | Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell. |  | 7 |
| 9767854581 | 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 |
| 9767854582 | Cytokinesis | At the end of telophase, actin fibers form an equator around the cell and contract, separating the cytoplasm into two daughter cells. |  | 9 |
| 9767854583 | Centriole | A paired cluster of microtubules near the nucleus in animal cells. This organelle organizes spindle fibers during mitosis. | 10 | |
| 9767854584 | Centromere | Region of a chromosome where the two sister chromatids attach to one another. Contains the kinetochore. | 11 | |
| 9767854586 | Spindle Fibers | Made of microtubules that connect centrioles to kinetochores of chromosomes and that separate sister (mitosis) or homologous (meiosis) chromosomes during cell division | 12 | |
| 9767854587 | Chromosome | A threadlike, gene-carrying structure found in the nucleus. Each chromosome consists of one very long DNA molecule and associated proteins. | 13 | |
| 9767854588 | Chromatid | One of two identical "sister" parts of a duplicated chromosome. | 14 | |
| 9767854589 | Haploid | A cell with only one copy of each chromosome. | 15 | |
| 9767854590 | Diploid | A cell with two copies of each chromosome. | 16 | |
| 9767854592 | G1 Checkpoint | Checks the cell before going into the S phase for damage. | 17 | |
| 9767854593 | cancer | Disorder in which some of the body's cells lose the ability to control growth; A disease in which the body cells grow & divide uncontrollably, damaging the parts of the body around them. | 18 | |
| 9767854594 | metastisis | spread of cancer cells | 19 | |
| 9767854595 | G2 Checkpoint | Checks to make sure that the DNA is copied correctly before going into the M phase | 20 | |
| 9767854596 | M phase | Makes sure that all the spindle is properly connected to the kinetochore. | 21 |
