Cell Cycle
Cell Cycle/Mitosis
| Term | Definition |
|---|---|
| Cell Cycle | Regular sequence of growth and division that cells undergo |
| Cancer | A disease in which abnormal cells divide uncontrollably |
| Interphase | Longest part of the cell cycle (G1, G0, S, G2) |
| G1 | Cell grows and new organelles form |
| G2 | Prepares for m phase and nuclear division |
| S | DNA Replication |
| What does PMAT stand for? | Prophase, Metaphase, Anaphase, Telophase |
| Prophase | Chromosomes become visible; nuclear envelope dissolves; centrioles and spindle fiber form |
| Centromere | The center piece that holds sister chromatids together |
| Metaphase | Sister chromatids line up in the middle |
| Anaphase | The spindle fiber pulls the sister chromatids apart forming individual chromosomes |
| Telophase | Nuclear envelope forms; spindle fiber dissolves |
| Cytokinesis | Cytoplasm divides |
| How many daughter cells are made during the cell cycle? | 2 |
| Are the cells identical or different? | Identical |
| Number of chromosomes for humans | 46 |
| diploid | 2n |
| haploid | n |
| spindle fiber | pulls sister chromatids apart to form individual chromsomes |
| What type of reproduction uses mitosis? | asexual |
| somatic cells | body cells (all cells other than egg and sperm) |
