A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis. In living organisms, primers are short strands of RNA. A primer must be synthesized by an enzyme called primase, which is a type of RNA polymerase, before DNA replication can occur.
The polymerase chain reaction (PCR) is a powerful core molecular biology technique. It is an efficient and rapid in vitro method for enzymatic amplification of specific DNA or RNA sequences from nucleic acids of various sources.A simple PCR reaction consists of a set of synthetic oligonucleotide primers that flank the target DNA sequence, target DNA, a thermostable DNA polymerase and dNTPs.he polymerase chain reaction (PCR) is a powerful core molecular biology technique.
