| Term | Definition |
|---|---|
| Mitosis | Process of asexual reproduction of cells |
| Cytokinesis | A moment in time when two new cells separate during cell division |
| Chromosome | A compact section of DNA, found in the nucleus. |
| Centriole | Produce spindle fibers |
| Chromatid | Thickened strands of copied DNA |
| Spindle Fibers | Produced by the centrioles, attach to the chromosomes at the centromere and pull them apart during anaphase. |
| Genes | A specific sequence of DNA that codes a specific trait. |
| DNA | deoxyribonucleic acid, found in the nucleus. |
| Chromatin | Long, thin strands of DNA that is found in the nucleus during interphase. |
| daughter cells | the new cells that are formed by cell division |
| Cell Cycle | the complete life cycle of a cell, included interphase, mitosis/meiosis and cytokinesis |
| Interphase | Normal functioning stage of the cell, growth and DNA replication happens at the end of this phase. |
| Prophase | First phase of mitosis in which the chromosomes shorten and thicken, nuclear membrane breaks down |
| Metaphase | Second phase of mitosis, chromosomes line up in the center of the cell, spindle fibers attach to the centromere. |
| Anaphase | Third phase of mitosis, chromosomes separate and are pulled toward the centrioles. |
| Telophase | Fourth phase of mitosis, nuclear membrane reforms, cell membrane pinches inward. |
