Hensikten med en primer er binding til bestemte sekvenser i DNA og muligheter for amplifisering (produksjon) av bestemte områder i større DNA-molekyler. A primer is a short strand of RNA or DNA (generally about 18-bases) that serves as a starting point for DNA synthesis. It is required for DNA replication .

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.

OR Enter the DNA Sequence (numbers are OK, but comments should be removed) . This string of nucleotides, called a primer , attaches to the beginning of the template strand by base pairing. DNA polymerase is then able to add the next . Hypothetically, a single DNA molecule could be copied into millions of molecules. Before we examine the details of the PCR reaction, the DNA primers must be .
