Mutations in proto-oncogenes that produce hyperactive forms become
- Acheck_circle
Oncogenes that drive uncontrolled cell division
- B
Apoptotic genes that trigger programmed cell death
- C
Tumor suppressors that halt the cell cycle
- D
Heritable plasmids that transfer between cells
Explanation
Normal proto-oncogenes (e.g., Ras) regulate growth; mutated overactive forms become oncogenes that push the cell to divide inappropriately.
