### Understanding Tumor Suppressor Genes

**Quiz Question:**

Which one of these is a tumor suppressor gene?
- ○ myc
- ○ erbB
- ○ Rb
- ● Gasp

In this multiple-choice question, learners are asked to identify which of the listed genes is a tumor suppressor gene.

**Explanation of Choices:**
- **myc**: This is an oncogene involved in cell cycle progression, apoptosis, and cellular transformation.
- **erbB**: This is also an oncogene that plays a role in the regulation of cell growth and differentiation.
- **Rb**: This is indeed a tumor suppressor gene involved in the regulation of the cell cycle. The Rb gene can prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide.
- **Gasp**: This is a fictional gene and not actually a known player in tumor suppression or oncogenesis.

**Correct Answer:**
- ○ Rb (Despite the highlighted "Gasp" answer in the image, Rb is the correct tumor suppressor gene in this context.)
