Cell Growth and Divv
Cell Growth and Division
| Question | Answer |
|---|---|
| cell division | the process by which a cell divides into two new daughter cells |
| mitosis | the first stage; division of the cell nucleus |
| cytokinesis | the second stage; division of the cytoplasm |
| chromatids | one of two identical "sister" parts of a duplicated chromosome |
| centromeres | the area where each pair of chromatids is attached; usually located near the middle of the chromatids |
| interphase | period of the cell cycle between cell divisions |
| cell cycle | the series of events that cells go through as they grow and divide |
| prophase | the first and longest phase of mitosis; chromosomes become visible |
| centrioles | two tiny structures located in the cytoplasm near the nuclear envelope |
| spindle | a fanlike microtubule structure that helps separate the chromosomes |
| metaphase | the second phase of mitosis; chromosomes line up across the center of the cell |
| anapahase | the third phase of mitosis; centromeres that join the sister chromatids split, allowing sister chromatids to separate and become individual chromosomes |
| telophase | the fourth and final phase of mitosis; chromosomes begin to disperse into a tangle of dense material, nuclear envelope re-forms |
| cyclin | regulates the timing of the cell cycle in eukaryotic cells |
| cancer | a disorder in which some of the body's own cells lose the ability to control growth |
