Read the following statements and choose the correct option 1.Carcinogens are agents that can induce the transformation of normal cells into cancerous neoplastic cells. 2.Both ionizing radiations like X-rays and non-ionizing radiations like UV can cause DNA damage leading to cancer. 3.Tobacco smoke contains chemical carcinogens that have been linked to lung cancer. 4.Oncogenic viruses have viral oncogenes that can le

Step-by-step solution

Transformation of normal cells into cancerous neoplastic cells may be induced by physical, chemical or biological agents. These agents are called carcinogens. Ionising radiations like X-rays and gamma rays and non-ionizing radiations like UV cause DNA damage leading to neoplastic transformation. The chemical carcinogens present in tobacco smoke have been identified as a major cause of lung cancer. Cancer causing viruses called oncogenic viruses have genes called viral oncogenes. Furthermore, several genes called ce
