Solid-Phase In Vitro Mutagenesis Using a Plasmid DNA Template,he PCR products. Alternatively, PCR amplification is used to create recombinant plasmid circles with discrete, cohesive single-stranded ends (.). This method also requires purification steps to remove excess primers. These circles, formed without the use of restriction enzyme digestion or ligation,
