Which of the following molecular diagnostic techniques is used to detect the presence of a pathogen in its early stage of infection?
1 X-ray
2 Polymerase Chain Reaction
3 Blood routine
4 Radiography
Explanation:
PCR helps in early detection of pathogens by amplification of their nucleic acids. Thus, very low concentration of bacteria or virus can be detected by this technique.

For effective treatment of the disease, early diagnosis and understanding its pathophysiology is very important. Which of the following molecular diagnostic techniques is very useful for early detection.
1 Western Blotting Technique
2 Southern Blotting Technique
3 ELISA Technique
4 Hybridization Technique
Explanation:
ELISA or Enzyme-Linked Immunosorbent Assay is based upon antigen-antibody reactions. By detecting the presence of antigens (pathogen proteins) in the patient's serum, or by detecting antibodies produced against the pathogen, ELISA may diagnose infections. An early diagnosis opens the door to future care and treatment. It helps people to plan ahead while they are still able to make important decisions on their care and support needs and on financial and legal matters.

Which of the following techniques is based on the principle of antigen-antibody interaction?
1 PCR
2 ELISA
3 Recombinant DNA technology
4 Gene therapy
Explanation:
ELISA is based on the principle of antigen-antibody interactions. It can detect infections caused by pathogens by detecting the presence of antigens (proteins, glycoproteins etc) or by antibodies synthesised against the pathogen.

Now a days it is possible to detect the mutated gene causing cancer by allowing radioactive probe to hybridise its complimentary 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 appears 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.
Explanation:
A single stranded DNA or RNA joined with a radioactive molecule (probe) is allowed to hybridized to its complementary DNA in a clone of cells. It is followed by detection using autoradiography. the clone having the mutated gene will not appear on the photographic film, because the probe will not have the complementary with the mutated gene.
