Cell Cycle
The Cell Cycle.
| Term | Definition |
|---|---|
| Prophase | First stage in mitosis, nuclear envelope dissolves. |
| Centriole | Origin of spindle fibers. |
| Equator | Where chromosomes align during metaphase. |
| Centromere | Holds sister chromatids together. |
| Anaphase | Sister chromatids get pulled apart. |
| Daughter Cell | One of the two cells at the end of mitosis. |
| Telophase | Last stage of mitosis, nuclear envelope reforms. |
| Diploid | Cell containing the full complement of chromosomes. |
| Interphase | Longest portion of cell cycle. |
| Synthesis | Put together or copy. |
| Cytokinesis | Division of cytoplasm and organelles. |
| Chromatin | Relaxed form of DNA. |
| Chromosome | DNA containing structure. |
| Sister Chromatids | Contains identical copies of DNA held together. |
| Spindle Fiber | Structure used to move DNA into position. |
| Metaphase | Middle phase of mitosis, DNA lines up at equator. |
| Crossing Over | Chromosomes swapping genetic material during metaphase I. |
| Haploid | Cell containing half the full complement of chromosomes. |
| Gamete | Reproductive cell made through meiosis (egg or sperm cell). |
| Cell Cycle | Cycle of growing and dividing that cells reproduce by. |
| Mitosis | Stage of the cell cycle during which the cell's nucleus and nuclear material divide. |
| Cyclin | One of the specific proteins that regulate the cell cycle. |
| Cyclin-Dependent Kinase | Enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle. |
| Cancer | Uncontrolled growth and division of cells. |
| Carcinogens | Substances and agents that are known to cause cancer. |
| Apoptosis | Programmed cell death. |
| Stem Cells | Unspecialized cells that can develop into specialized cells when under the right conditions. |
