Biotechnology and its Applications

Nowadays it is possible to detect the mutated gene causing cancer by allowing a radioactive probe to hybridise with its complementary DNA in a clone of cells, followed by its detection using autoradiography, because:

  1. A.The mutated gene partially appears on a photographic film
  2. B.The mutated gene completely and clearly appears on a photographic film
  3. C.The mutated gene does not appear on a photographic film as the probe has no complementarity with it
  4. D.The mutated gene does not appear on a photographic film as the probe has complementarity with it

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
