B. a housekeeping gene.

Cancer

Cancer occurs when cell growth is uncontrolled and cell death is inhibited. It usually arises from an interplay of genetics and external factors such as physical, chemical, and biological carcinogens. Some risk factors for cancer are smoking, being overweight or obese, and an unhealthy diet and lifestyle. The most aggressive cancers include brain and pancreatic cancers whereas cancers with the best prognosis are melanoma, testicular cancer, Hodgkin lymphoma, breast cancer, and others.

Cancer can be caused by genetic factors, where a cell's genome, or DNA, grows differently than it would normally. Explore the features of genetics in this process through proto-oncogenes, mutation and tumor suppressor genes like the famous p53 gene.
