== Process == Genomic DNA is digested with restriction enzymes, circularized by hybridisation to selectors and subsequently attached to a vector sequence by ligation. The procedure results in circular DNA molecules with an included general primer pair motif that can be used for amplification by PCR or RCA.
==Selector construct==
A selector consists of two oligonucleotides, one '''Vector''' oligonucleotide and one '''Selector probe'''.<ref name="Isaksson" /> Together they form one '''Selector''' with target specific ends on each side of a general primer motif.
==Selection mechanisms==
# A selector probe hybridizes with both ends of the selected target. # A selector probe hybridizes with one end to the 3’ end of the target and the other end to an internal sequence of the target. The protruding 5' end is cleaved off using Taq polymerase.
