Nowadays, it is possible to detect the mutated gene causing cancer by allowing the radioactive probe to hybridise its complementary DNA in clone of cells, followed by its detection using autoradiography because:
| 1. | mutated gene does not appear on a photographic film as the probe has no complementarity with it. |
| 2. | mutated gene does not appear on a photographic film as the probe has complementarity with it. |
| 3. | mutated gene partially appears on a photographic film. |
| 4. | mutated gene completely and clearly appears on a photographic film. |
