Hint: The PCR technique is the technique which is useful to make many copies of a specific DNA region in vitro. The PCR is the thermostable DNA polymerase, Taq polymerase and requires DNA primers designed specifically for the DNA region of interest.

Complete answer: The scientist Karry Mullis invented the polymerase chain reaction technique (PCR technique), which also earned him the Nobel Prize in the field of Chemistry. He died because of the disease called pneumonia in August. According to sources, he was seventy-four years old when he died. The Polymerase Chain Reaction (PCR) technique also allows the scientists to make millions of the copies of a scarce sample of the DNA. This technique has revolutionized many aspects of the current research, which includes the diagnosis of the genetic defects and the detection of the AIDS virus in the human cells. The PCR is also used in many research labs, and it also has practical applications in forensics, genetic testing, and for diagnostics also. The PCR is used to amplify the genes associated with the genetic disorders from the DNA of the patients. The polymerase chain reaction (PCR) is the technology used for the quick and easy amplifying of the DNA sequences, which is based on the principle of the enzymatic replication of the nucleic acids. It is the method that has an important role in the field of molecular biology and constitutes one of the basic methods for DNA analysis.
Therefore, the correct answer is option B.

Note: The Polymerase Chain Reaction (PCR) is an important tool for many of the applications. For example, it can be used to amplify a sample of the DNA when there is not enough to analyze as a method of identifying a gene of the interest or to test for the disease.
