| Term | Definition |
|---|---|
| Binary fission | Type of cell division that occurs in prokaryotic cells in which a parent cells divides into identical daughter cells. |
| Cancer | Disease that occurs when the cell cycle is no longer regulated and cells divide out of control. |
| Cell cycle | Repeating series of events that a cell goes through during its life, including growth, DNA, synthesis, and cells division. |
| Cell division | Process in which a parent cell divides to formtwo daughter cells. |
| Cytokinesis | Splitting of the cytoplasm to form daughter cells when a cell divides. |
| DNA replication | Process of copying of DNA prior to cell division |
| Interphase | Stage of the eukaryotic cell cycle when the cell grows, synthesizes DNA, and prepares to divide. |
| Mitosis | Process in which the nucleus of a eukaryotic cell divides. |
| Tumor | Abnormal mass of cells that may be cancerous. |
| Anaphase | Third phase of mitosis during which sister chromatids separate and move to opposite poles of the cell. |
| Centromere | a constricted region of the chromosome and separates the short arm (also known as the p arm) and the long arm (also known as the q arm) of the chromosome. |
| Chromatid | one of the two identical halves of a chromosome that has been replicated in preparation for cell division. |
| Chromatin | a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms. |
| Gene | the basic physical and functional unit of heredity. |
| Homologous chromosomes | Homologous chromosomes are defined as pairs of chromosomes in a diploid organism that have the same content and order of genes but may contain different gene variants, or alleles. |
| Metaphase | a stage during the process of cell division (mitosis or meiosis). |
| Prophase | the first stage of mitosis or the second division of meiosis in which chromosomes become visible as tightly coiled threadlike structures |
| Telophase | the last step of cell division, when chromosomes move in opposite directions so two new cells can be formed from one |
