title: New type of linker useful for cloning experiments.
abstract: A new class of linker oligodeoxynucleotide sequences is described which allows the original sequence of a foreign DNA to be restored after cloning. In the standard linker approach the terminal base pairs of the linker-sequences are irreversibly attached to the cloned DNA, thus altering the genetic information. The use of the new type of linker is demonstrated by the transformation of the unique Pvu II site in pBR322 into Bam HI site using the ISO ('in-site-out') linker d(GATCCGGATC). Possible further applications of these linker sequences are described.
