Define Mitosis | A type of cell division that results in two daughter cells each the same as the parent nucleus, |
Define Meiosis | A type of cell division that results in two daughter cells each with half the chromosome number of the parent cell. |
Define Interphase | The resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. |
Define Prophase | The first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear |
Define Metaphase | The second stage of cell division during which the chromosomes become attached to the spindle fibers. |
Define Anaphase | The stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle. |
Define Telephase | The final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the... |
Define Sister Chromatids | are 2 identical copies of a chromatin connected by a centromere. Compare sister chromatids to homologous chromosomes |
Define Centromere | The point on a chromosome by which it is attached to a spindle fiber during cell division |
Define Spindle Fiber | is the structure that separates the chromosomes into the daughter cells during cell division |
Define Centriole | A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in |
