    Abstract:
    Basic to the development of long-range physical maps of DNA are the detection and localization of landmarks within recombinant clones. Sequence-tagged sites (STSs), which are short stretches of DNA that can be specifically detected by the polymerase chain reaction (PCR), can be used as such landmarks. Our interest is to construct physical maps of whole human chromosomes by localizing STSs within yeast artificial chromosome (YAC) clones. Here we describe a generalized strategy for the systematic generation of large numbers of STSs specific for human chromosome 7. These STSs can be detected by PCR assays developed following the sequencing of anonymous pieces of chromosome 7 DNA, which was derived from flow-sorted chromosomes or from lambda clones made from DNA of a human-hamster hybrid cell line. Our approach for STS generation is tailored for the development of PCR assays capable of screening a large YAC library. In this study, we report the generation of 100 new STSs specific to human chromosome 7.
