Question

Tumor suppressor genes function to
A) prevent gene expression of oncogenes.
B) prevent release of growth factors.
C) slow down unchecked cell growth, differentiation, division, or adhesion.
D) produce proto-oncogenes.
E) stimulate metastasis.

Tumor suppressor genes help regulate cell growth by slowing down cell division, repairing DNA mistakes, or telling cells when to die (a process known as apoptosis). They act as a brake on cell proliferation, preventing unchecked cell growth that can lead to cancer.
