A
mutated gene partially appears on a photographic film.
B
mutated gene completely and clearly appears on a photographic film.
C
mutated gene does not appear on a photographic film as the probe has no complimentarity with it.
D
mutated gene does not appear on photographic film as the probe has complimentarity with it.
