Question

Now a days it is possible to detect the mutated gene causing cancer by allowing a radioactive probe to hybridize its complimentary DNA in a clone of cells, followed by its detection using autoradiography because ______

Options

• mutated gene completely and clearly appears on a photographic film.

• mutated gene does not appear on a photographic film as the probe has no complimentarity with it.

• mutated gene does not appear on photographic film as the probe has complimentarity with it.

• mutated gene partially appears on a photographic film.

Answer 1

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 the mutated gene does not appear on a photographic film as the probe has no complementarity with it.
