Explanation:
Detailed explanation-1: -A mutated (changed) form of a type of gene called a proto-oncogene, which is involved in normal cell growth and division. When a proto-oncogene is changed so that too many copies are made or it becomes more active than normal, it is called an oncogene.
Detailed explanation-2: -Often, proto-oncogenes encode proteins that function to stimulate cell division, inhibit cell differentiation, and halt cell death.
