B. Cellular oncogenes
Step-by-step solution
Malignant tumors are a mass of proliferating cells that grow rapidly, invading and damaging the surrounding normal tissues.Both ionizing radiations such as X-rays and gamma rays, as well as non-ionizing radiations such as UV, cause DNA damage leading to neoplastic transformation. Cancer-causing viruses, also known as oncogenic viruses, have genes called viral oncogenes Several genes called cellular oncogenes or proto oncogenes have been identified in normal cells which, when activated under certain conditions, coul
