The various components required for PCR include a DNA sample, DNA primers, free nucleotides called ddNTPs, and DNA polymerase.

With the technique called polymerase chain reaction (PCR), scientists can make multiple copies of a specific genetic sequence within DNA. PCR is a powerful tool for researchers because it allows for ...

Scientists Can Make Copies of a Gene through PCR

Once scientists have zeroed in on a specific segment of DNA, how do they produce enough copies of that segment for their research? In most cases, the polymerase chain reaction, or PCR, is their method ...
