Mitosis
| Term | Definition |
|---|---|
| mitosis | The process in cell division by which the nucleus divides, consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes. |
| cell cycle | a series of events that take place in a cell leading to duplication of its DNA |
| cell division | division of a cell into two daughter cells with the same genetic material |
| replication | The process of duplicating or producing an exact copy of a cell |
| chromatin | material that is made up of DNA and RNA that you find in chromosomes |
| chromatid | one-half of two identical copies of a replicated chromosome |
| chromosome | A structure in all living cells that consists of a single molecule of DNA bonded to various proteins and that carries the genes determining heredity. |
| centromere | the middle region of a chromosome that connects the two chromatids |
| cytokinesis | the splitting of the cytoplasm |
| centrioles | part of the cell that turns into spindle fibers to pull apart the chromatids in metaphase |
| daughter nuclei | two nuclei that result from the division of a single nucleus |
| clone | cell or cells that is produced asexually from and is genetically identical to a single ancestor. |
| diploid (number) | a cell that consists of two sets of chromosomes. 2(n) |
| asexual reproduction | type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only |
| interphase | the resting phase between successive mitotic divisions of a cell |
| cell plate | a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells |
| binary fission | a type of asexual reproduction wherin a cell divides giving rise to two cells. |
| grafting | technique done by scientists to attach tissue of one plant to another |
| cancer | disease in which abnormal cells divide uncontrollably |
| prophase | first stage of mitosis in which the chromosomes become visible as paired chromatids and the nuclear membrane disappears |
