[Cloning of the gene for thermostable Thermus aquaticus YT1 DNA polymerase and its expression in Escherichia coli].

Using the phasmid vector pSL5, the genomic DNA fragment of T. aquaticus YT1 which contained the thermostable DNA polymerase (Taq-polymerase) gene was cloned. The BglII fragment of this genome locus was subcloned in the BamHI site of the pUC19 plasmid.
