...multimerization of the PCR primers can cause duplication of the primer sequence in the resulting plasmid...proximal to the target site, can identify these duplications (slightly larger bands sizes relative to the...percentage agarose gel (~3%). Note that primer duplication will evade detection in the initial RFLP analysis...because the introduced restriction site is also duplicated.
