Question

Quizplus · Accepted Answer

Proto-oncogenes are genes that have the potential to become oncogenes, which promote uncontrolled cell growth and division leading to cancer. Proto-oncogenes can code for proteins involved in cell growth, such as growth factors, receptors, and signaling molecules. When mutated or overexpressed, proto-oncogenes can transform into oncogenes and promote abnormal growth and division of cells.
