The laboratory technique in which small amounts of DNA from a microorganism are amplified and then used to identify the organism is

Question

Quizplus · Accepted Answer

The laboratory technique described is Polymerase Chain Reaction (PCR), which is used to amplify small amounts of DNA in a sample for identification purposes. Option A (hybridisation) involves the binding of nucleic acid probes to complementary sequences, but does not involve amplification. Option B (complement fixation) and Option C (radioimmunoassay) both involve the use of antibodies rather than DNA amplification. Option D (a nucleic acid probe) is a type of hybridisation technique, but it does not involve amplification like PCR.
