E)normally promote oncogenesis.

Question

Quizplus · Accepted Answer

Proto-oncogenes are genes that encode important proteins involved in processes such as the control of cell cycle. They can become overactivated and mutated into cancer-promoting oncogenes, leading to uncontrolled cell growth and division. However, in their normal state, proto-oncogenes play important roles in regulating cell growth and division.
