• B. No other technique is available
• C. PCR has to be done before hybridization can be done
• D. It amplifies the genetic material

Answer 1

The correct option is D It amplifies the genetic material

AIDS can be detected by PCR (polymerase chain reaction) at early stages as it amplifies the genetic material millions of times. Thus the presence of even a tiny number of viruses can give a positive result to the diagnostic test.
