Cell Cycle: Phases
Interphase, Mitosis, and Cytokinesis
| Question | Answer |
|---|---|
| During this phase normal cell functions occur as well as cell growth | Gap 1 (G1) |
| During this phase DNA replicates producing 2 copies of each chromosome | Synthesis (S) |
| During this phase the cell will continue to grow. At the end of this phase is a checkpoint to determine if the cell can now proceed to enter mitosis. | Gap 2 (G2) |
| The process of the division of the cell nucleus in which the chromosomes divide into 2 identical sets. This process is divided up into 4 phases (prophase, metaphase, anaphase, and telophase) | Mitosis |
| The following occurs during this phase: Nuclear membrane begins to disappear, the replicated centrioles begin to move to opposite ends of the cell, spindle fibers begin to form between the centrioles, DNA thickens up and coils | Prophase |
| The following occurs during this phase: Nuclear membrane is absent, centrioles are at opposite ends of the cell, chromosomes are attached to their own spindle fiber at the centromere, the chromosomes line up in the center of the cell | Metaphase |
| The following occurs during this phase: the sister chromatids and centromeres split apart and move to opposite ends of the cell. | Anaphase |
| The following occurs during this phase: spindle fibers break down and begin to disappear, nuclear membrane begins to reform, the cytoplasm and cell membrane begin to pinch in at the center of the cell | Telophase |
| The following occurs during this phase: Two new daughter cells are formed. | Cytokinesis |
| A period of cell growth and development. Divided up into 3 parts (G1, S, and G2) | Interphase |
| series of events that cells go through as they grow and divide | Cell Cycle |
