In order to happen DNA synthesis of a wanted portion of DNA in laboratory, the DNA polymerases that preform that synthesis need to have a an existing strand of nucleotides already in order to attach new DNA nucleotides. To that existing strand of nucleotides we call primer. In a lab, scientists synthesize DNA primers through specific sequences that bind to other sequences of a single-thread DNA molecule and these are the primers commonly used to perform PCR.

Existing strand of nucleotides we call primer.Synthesize DNA primers through specific sequences that bind to other sequences of a single-thread DNA molecule.

Where do primers come from in PCR?

A primer must be synthesized by an enzyme called primase, which is a Kind of RNA polymerase, before DNA replication can occur.

The making of a primer is require because the enzymes that synthesize DNA, which are called DNA polymerases,  only linked to new DNA nucleotides to an strand of nucleotides.

Thus,  DNA primers through specific sequences that bind to other sequences of a single-thread DNA molecule.
