Phase 2 – Dynamic Understanding
► Investigation Three Summary – Normal and Cancerous Tissue
In Investigation Three, you explored the process of cell division in normal and in cancerous tissue. During this Investigation, you:
1. Examined the role of contact inhibition in preventing cells from continuously dividing.
2. Modeled what happens when a normal cell is transformed into a cancerous cell.
3. Viewed and compared prepared slides of normal and cancerous lung and breast tissue under a microscope.
► Investigation Three Summary – Learning Goals
Through these experiments, you concluded that:
1. Normally the cell cycle is regulated so that cell only progress through the cycle and divide when necessary. In cancer, the regulation of the cell cycle is lost and the cell divides constantly. The constant cell proliferation leads to a tumor and cancer.
