Linker and/or adapter molecules can be joined to the cut ends. Linkers are short, chemically synthesized, double-stranded oligonucleotides, which contain within them one or more restriction endonuclease sites, e.g., linker 5'CCGAATTCGG (only one strand of the linker is shown here) contains one EcoRI site.
