Primer dimers may be visible after gel electrophoresis of the PCR product. PDs in ethidium bromide-stained gels are typically seen as a 30-50 base-pair (bp) band or smear of moderate to high intensity and distinguishable from the band of the target sequence, which is typically longer than 50 bp.

Primer extension can be used to determine the start site of transcription (the end site cannot be determined by this method) by which its sequence is known. This technique requires a radiolabelled primer (usually 20 - 50 nucleotides in length) which is complementary to a region near the 3' end of the mRNA.
The central subdomain forms a toprim fold which is made of a mixture five beta sheets and six alpha helices. [ 4 ] [ 8 ] The toprim fold is used for binding regulators and metals. The primase uses a phosphotransfer domain for the transfer coordination of metals, which makes it distinct from other polymerases. [ 4 ]
