| anaphase | The third subphase of mitosis, in which the chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell |
| anchorage dependence | requirement that to divide, a cell must be attached to the substratum |
| asexual reproduction | type of reproduction involving only one parent that produces genetically identical offspring by budding or by the division of a single cell or the entire organism into two or more parts |
| autosome | chromosome that is not directly involved in determining sex, as opposed to a sex chromosome |
| benign tumor | mass of abnormal cells that remains at the site of origin |
| binary fission | type of cell division by which prokaryotes reproduce. Each dividing daughter cell receives a copy of the single parental chromosome |
| cancer cells | Do not have a properly functioning cell-cycle system; instead, they divide excessively and can invade other tissues of the body |
| carcinomas | Cancers that originate in the external or internal coverings of the body |
| cell cycle | ordered sequence of events in the life of a eukaryotic cell, from its origin in the division of a parent cell until its own division into two; composed of the M, G1, S, and G2 phases |
| cell cycle control system | cyclically operating set of molecules in the cell that triggers and coordinates key events in the cell cycle |
| cell division | The reproduction of cells |
