| Caption: | The Polymerase Chain Reaction (PCR): The polymerase chain reaction, or PCR, is a powerful method for multiplying DNA molecules by up to a billionfold in a test tube, yielding large amounts of specific genes for a host of applications in molecular biology. The reaction begins with a solution containing a DNA sample, DNA primers that are specific for the target DNA sequence, deoxynucleoside triphosphates (dNTPs), and a heat-stable DNA polymerase. |
