The three-step PCR process, or polymerase chain reaction, is used to amplify or copy DNA sequences. First, the two strands of DNA separate. Second, RNA primers anneal or attach to the DNA. Third, heat stable polymerase c... More »

A PCR machine, also known as a thermal cycler, is a DNA amplifier that regulates temperature and amplifies segments of DNA via the polymerase chain reaction. As Wikipedia points out, PCR machines are also sometimes used ... More »

A polymerase chain reaction, or PCR, consists of three steps: DNA denaturation, primer annealing and extension. These steps are repeated between 20 and 35 times to synthesize the correct quantity of the DNA of interest. ... More »

A PCR primer, or polymerase chain reaction primer, is a short segment of DNA that researchers use to amplify, or replicate, a targeted portion of the DNA molecule. This results in billions of copies of the targeted area ... More »

PCR, or polymerase chain reaction, uses repeating cycles of heating and cooling to replicate strands of DNA from a sample. PCR can amplify and copy a single gene from a sample multiple times. More »
