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 »

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 »

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 »

PCR in biology stands for polymerase chain reaction. It refers to a process of multiplying or amplifying a small amount of DNA to carry out more conclusive research or data analysis. More »

Primers are small DNA sequences that are designed to start DNA replication in a laboratory technique called polymerase chain reaction, or PCR, to amplify certain segments of DNA. Forward and reverse primers differ in the... More »
