title: Characterization of the distribution of potential short restriction fragments in nucleic acid sequence databases. Implications for an alternative to chemical synthesis of oligonucleotides.
abstract: We have searched the GenBank nucleic acid sequence database for potential short restriction fragments. All possible oligonucleotides up to length five are found at least once flanked by known restriction recognition patterns. Thus, searches in the database for a specific sequence corresponding to a desired oligonucleotide would often point to one or more sources of short, retrievable fragments containing that sequence. These results underscore the potential of nucleic acid sequence databases in planning experiments.
