A method is presented for the rapid in vitro amplification of DNA sequences that flank a region of known sequence. The method uses the polymerase chain reaction (PCR), but it has the primers oriented in the reverse direction of the usual orientation. The template for the reverse primers is a restriction fragment that has been ligated upon itself to form a circle. This procedure of inverse PCR (...

background: splicing by overlap extension (soe) pcr is used to create mutation in the coding sequence of an enzyme in order to study the role of specific residues in protein’s structure and function.objectives: we introduced a nested-soe-pcr (n –soe-pcr) in order to increase the specificity and generating mutations in a gene by soe-pcr.  materials and methods: genomic dna from bacillus thermoca...
