Mitosis review
Mitosis
| Term | Definition |
|---|---|
| Mitosis | Process that forms two new nuclei, each with complete copies of DNA |
| DNA | Contains information that determines the traits of living things; packaged into structures called chromosomes. |
| Chromosomes | Made of chromatin and DNA |
| Cell Cycle | Life cycle of the cell, has three stages, interphase, mitosis and cytokinesis |
| Interphase | Part of cell cycle when cell is NOT dividing |
| Cytokinesis | Occurs during last phase of cell cycle; cytoplasm divides and two new cells form |
| Unicellular | Single-celled organism |
| Multicellular | Having many cells |
| Prophase | Chromosomes condense and become visible under a microscope, the membrane around the nucleus breaks down. |
| Anaphase | Chromosomes separate and are pulled to opposite sides of the cell. |
| Telophase | Last phase of mitosis, new nuclear membrane forms around each group of chromosomes. Chromosomes become less and cytokinesis begins |
| Metaphase | Chromosomes line up in the middle of the cell |
| Meiosis | Type of cell division that produces cells for sexual reproduction. |
| Sex Cell | Controls development of sex characteristics |
| Homologous chromosome | Have the same genes in the same sequences and have the same structure, but alleles may differ. |
