Phase 2 – Dynamic Understanding
► Investigation Two Summary – Lab Goals
In Investigation Two, you explored the factors that determine cell division and replication. During this Investigation, you:
1. Constructed a model of the cell cycle using tubing including the following phases:
- G1 Phase
- S Phase
- G2 Phase
- M Phase
2. Identified the following sub-phases of M Phase as:
- Prophase
- Metaphase
- Anaphase
- Telophase
3. Altered the cell cycle model to show how the cell stops and starts each phase.
► Investigation Two Summary – Learning Goals
Through these experiments, you concluded that:
1. Tissues replenish cells through cell division. Cell division has four phases, G1, S, G2, and M phase. During the S phase DNA is replicated and during the M phase mitosis occurs and cytokinesis (cell division occurs). Mitosis can be broken down into four stages including prophase, metaphase, anaphase, and telophase.
2. The cell cycle is regulated by different proteins. The time it takes for a cell to complete the cycle is dependent on which regulatory proteins are present in that cell at any given time.
