Quizplus · Accepted Answer

Tumor suppressor genes, such as p53, normally function to inhibit the development of cancer by regulating cell growth and division. When the DNA is damaged, p53 functions to halt the cell cycle and repair the damage or induce apoptosis, which prevents the proliferation of potentially harmful cells. Mutations in tumor suppressor genes can result in their loss or malfunction, leading to uncontrolled cell growth and the development of cancer.
