Abstract:From human chromosome 21-specific libraries, 22 SfiI linkingclones and 38 P1 clones were isolated and regionally mappedon the chromosome. The terminal sequences of these clones weredetermined and pairs of PCR primers were generated which couldspecifically amplify the sequenced regions. These sequence-taggedsites (STSs) should be useful for constructing a high resolutionmap of human chromosome 21.
Keywords:human chromosome restriction enzyme SfiI  linking clone  P1 clone  high-resolution physical map  PCR
