Identify the molecular diagnostic technique from the following:
(A) Enzyme Linked Immuno Sorbent Assay
(B) Polymerase Chain Reaction
(C) Cloning
(D) Recombinant DNA Technology
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A), (B) and (D) Only
(A) Enzyme Linked Immuno Sorbent Assay — True.
(B) Polymerase Chain Reaction — True.
(C) Cloning — False. Cloning makes copies of DNA; it is not a diagnostic test.
(D) Recombinant DNA Technology — True.
NCERT Extract:
Molecular Diagnosis – “… You know that for effective treatment of a disease, early diagnosis and understanding its pathophysiology is very important. Using conventional methods of diagnosis (serum and urine analysis, etc.) early detection is not possible. Recombinant DNA technology, Polymerase Chain Reaction (PCR) and Enzyme Linked Immuno-sorbent Assay (ELISA) are some of the techniques that serve the purpose of early diagnosis.”
