Deletion mutants are particularly useful in defining the boundaries of noncoding genetic functions. Such mutants can be precisely generated using synthetic oligodeoxyribonucleotides as mutagens. In this paper we describe the application of this method to recombinant DNA cloned in a phage M13-derived vector. The mutagenic oligodeoxyribonucleotides, 20 and 21 nucleotides in length, were used to delete a tract of 20 dA-dT base-pairs and an adjacent 22 base-pair perfect dyad from the ADR3 locus, the 5'-flanking regulatory region of the ADR2 gene, of Saccharomyces cerevisiae with high efficiency.
