Cell Division
Mitosis and Meiosis
| Question | Answer |
|---|---|
| Programmed cell death; leads to a decrease in the number of cells | Apoptosis |
| Interphase + Mitosis = ??? | The Cell Cycle |
| The longest phase of the cell cycle | Interphase |
| Phase when DNA doubles | Interphase |
| Multi-stage process leading to a disruption of normal cell division / behaviour; otherwise known as the development of cancer | Carcinogenesis |
| Genes that normally encode for proteins that promote the cell cycle | proto-oncogenes |
| Genes that normally encode for proteins that stop the cell cycle | tumor suppressor genes |
| 4 phases of Mitosis | Prophase, Metaphase, Anaphase, Telophase |
| Mitosis phase where cytokinesis occurs | Telophase |
| True or False: DNA replication occurs between Meiosis I and Meiosis 2 | FLASE. DNA replication only occurs during Interphase; there is no DNA replication during Meiosis |
| 2 ways in which Meiosis creates genetic variation | Crossing Over and Independent Assortment |
| Definition of Synapsis | Pairing up of homologous chromosomes |
