BS cell cycle
| Term | Definition |
|---|---|
| cell cycle | sequence of growth and division in a cell. |
| mitosis | period of nuclear cell division in which two daughter cells are formed, each containing a complete set of chromosomes. |
| interphase | period of cell growth. |
| cytokinesis | division of the cytoplasm. |
| prophase | the first and longest phase of mitosis; chromatin coils into visible chromosomes, the nuclear envelope disappears, and spindle forms. |
| metaphase | second phase of mitosis. chromosomes line up at the equator of the cell. |
| anaphase | third phase of mitosis; chromosomes split and are pulled apart towards opposite ends of the cell. |
| telophase | last phase of mitosis; 2 new nuclei are formed and the chromosomes uncoil. |
| daughter cell | term used to describe the new cells created during mitosis and meiosis. |
| cancer | uncontrolled cell division. |
| reproduction | production of offspring by an organism. |
| chromatin | long tangled strands of DNA found in the nucleus of a cell during interphase. |
| chromatids | two exact copies of DNA that make up a chromosome. |
| centromere | cell structure that joins the 2 sister chromatids of a chromosome. |
| chromosome | cell structure that carries genetic material that is copied and passed from generation to generation of a cell; consists of 2 sister cells connected by centromere. |
| spindle | cell structure composed of micro tubules that aid in the process of cell division by moving chromatids through the process. |
| aster | star shaped structure that forms around the centrioles during cell division; made of micro tubules. |
| cleavage furrow | indentations of the cell membrane that forms during cytokinesis in an animal cell; eventually pinches together, forming two new cells. |
| cell plate | precursor to the cell wall that forms during cytokinesis of a plant cell; forms into new cell wall; creates two new plant cells. |
| inhibition | slows or stops a process from happening. |
