It is important that a cell checks itself as it moves through the cell cycle. For instance, if mistakes have occurred or there is not enough food to support the cell through completion of a cycle, then the cell could end up making two daughter cells that can't survive, or even worse, make daughter cells that are so messed up that they injure the organism in some way. Question: On the diagram of the cell cycle below, draw 4 lines denoting the location of each of the 4 major cell cycle check points. Then for each, list one or more "chemical questions" that the cell asks itself at checkpoint before progressing. Pro P-M Meta Ana Telo G2 M S G1

Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

It is important that a cell checks itself as it moves through the cell cycle. For instance, if mistakes have occurred or there is not enough food to support the cell through the completion of a cycle, then the cell could end up making two daughter cells that can’t survive, or even worse, make daughter cells that are so messed up that they injure the organism in some way.
**Question:** On the diagram of the cell cycle below, draw 4 lines denoting the location of each of the 4 major cell cycle checkpoints. Then for each, list one or more “chemical questions” that the cell asks itself at the checkpoint before progressing.
**Diagram Explanation:**
The diagram represents the cell cycle divided into sections labeled G1, S, G2, and M.
- **G1:** Occurs after cell division; the cell grows and prepares for DNA synthesis.
- **S (Synthesis):** The phase where DNA replication takes place.
- **G2:** Prepares the cell for mitosis; the cell checks for DNA damage.
- **M (Mitosis):** Cell division occurs.
Around the M phase, subdivisions are indicated:
- **Pro:** Prophase
- **P-M:** Prometaphase
- **Meta:** Metaphase
- **Ana:** Anaphase
- **Telo:** Telophase
These subdivisions represent the stages of mitosis.
**Instructions for Students:**
Identify the checkpoints at G1, S, G2, and M phases. Consider what "chemical questions" the cell might ask at these checkpoints, such as checking for DNA damage, ensuring all necessary components are present, and verifying complete DNA replication.
