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