Abstract:
Twenty-five single-copy anonymous DNA markers for human chromosome 22 were isolated. These markers were assigned to four different regions on the chromosome. Six markers recognize restriction fragment length polymorphisms. The relative positions of five of these polymorphic markers on the framework map of chromosome 22 were determined by linkage analysis. The sizes of the NotI fragments recognized by 22 markers were determined by pulsed-field gel analysis. The total length of the NotI fragments identified is at least 12 Mb, which represents about 20% of the entire chromosome.
