What is the function of PCR?
A
Make copies of DNA
B
Delete a fragment of DNA
C
Identify a disease
D
Produce new fragments
Explanation: 

Detailed explanation-1: -Polymerase chain reaction (abbreviated PCR) is a laboratory technique for rapidly producing (amplifying) millions to billions of copies of a specific segment of DNA, which can then be studied in greater detail.

Detailed explanation-2: -Throughout the PCR process, DNA is subjected to repeated heating and cooling cycles during which important chemical reactions occur. During these thermal cycles, DNA primers bind to the target DNA sequence, enabling DNA polymerases to assemble copies of the target sequence in large quantities.

Detailed explanation-3: -Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.

Detailed explanation-4: -Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.

Detailed explanation-5: -With the technique called polymerase chain reaction (PCR), scientists can make multiple copies of a specific genetic sequence within DNA.
