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

Correct answer: (3) mutated gene does not appear on a photographic film as the probe has no complementarity with it.
