    Abstract:
    An approach to the directed genetic recombination in vitro has been devised, which allows for joining, in a predetermined chemical-enzymatic way, a series of DNA segments to give a precisely spliced polynucleotide sequence (DNA Splicing by Directed Ligation, SDL). The approach makes use of amplification, by several polymerase chain reactions (PCR), of the chosen DNA segments. The corresponding primers contain recognition sites of the class IIS restriction endonucleases, yielding protruding ends of unique primary structures. The protruding ends of the segments to be joined together are structurally predetermined to make them mutually complementary. Ligation of the mixture of the segments so synthesized gives the desired sequence in an unambiguous way. The suggested approach has been exemplified by the synthesis of a totally processed (intronless) gene encoding human mature interleukin-1 alpha.
