The table below identifies three classes of genes that affect the cell cycle.

Gene class Gene activity

proto-oncogenes regulate progresses though the normal cell

cycle

oncogenes cause uncontrolled cell cycle progression

tumor suppressor genes restrict cell cycle progression

Which would MOST likely be happening in cancer cells?

Oncogenes are active and tumor suppressor genes are active.
