Since its discovery in 1984, PCR has become fundamental to the field of microbiology. It is a simple technique with myriad applications, from criminal forensics to the detection of pathogens.How Does PCR Work? A polymerase chain reaction requires two types of reagents, DNA polymerase and primers...
During this process, each unique DNA molecule in the library is bound to the surface of a bead or a flow-cell and PCR amplified to create a set of identical clones. In the case of Ion Torrent technology, a process called “templating” is used to add library mole...
The qPCR workflow below delineates the steps in real-time PCR. First, amplification reactions are set up with PCR reagents and unique or custom primers. Reactions are then run in real-time PCR instruments and the collected data is analyzed by proprietary instrument software. ...

How a GC clamp can improve PCR primer specificity Binding between G and C bases is formed by three hydrogen bonds, compared to only two between adenine (A) and thymine (T) base pairs. Therefore, G and C base pairs are considered to have stronger binding than A and T base pairs. ...
The technique uses specific primers (short strands of nucleic acid needed to initiate DNA replication) and fluorescent probes to allow real-time quantification of target bacterial DNA during amplification. The qPCR assay is a mainstay of microbiological diagnostics within the National Health Service (...
Using both, forward and reverse primers is important for PCR to be successful. Exponential amplification cannot occur if only one primer is used because in this case, only one strand of dsDNA would get amplified, resulting in only one copy being produced per cycle. Additional resource...

If you performed a PCR reaction but accidentally only added one of the two primers, what would the product be? What would happen without DNA polymerase? For what purpose is the polymerase chain reaction (PCR) used? Why do you need a forward and reverse primer in PCR?
