उत्तर
Cancer causing genes are called oncogenes.
Explanation:
Cancer-causing genes are known as oncogenes. These genes are mutated or altered forms of normal genes called proto-oncogenes, which regulate cell growth and division. When oncogenes become activated, they can cause uncontrolled cell growth leading to cancer by producing abnormal proteins that drive cell proliferation.
