Question

question 35
the polymerase chain reaction can be used for identification of ______.

Explanation:

Polymerase Chain Reaction (PCR) amplifies DNA. Microorganisms have unique DNA sequences, so PCR identifies them. Antibodies (A) are proteins, PCR doesn't detect them directly. Proteins (C) aren't amplified by PCR. Growth characteristics (D) relate to culture, not PCR. So B is correct.

Answer:

B. microorganisms
