Question:

PCR is a useful tool for early diagnosis of an infectious disease. Elaborate.

Answer:

PCR (polymerase chain reaction) is used to amplify the nucleic acid (single copy of DNA into multiple) without using cells. Very low concentration of pathogens (bacteria, viruses) in the human body can be detected by amplification of their nucleic acid by using the technique PCR. When the source of DNA is impure, can be amplified by PCR technique. And when the sequence of HIV DNA is known, PCR method will help in the detection of HIV DNA in the blood or the tissues in suspected AIDS patients and to detect mutations in suspected cancer patients.
