摘要：A method is described for mapping of the DNA fragments of a human chromosome produced by restriction enzyme treatment of the total DNA from a hybrid cell containing a single human chromosome. The method involves production and selection of somatic cell mutants containing deletions of the human chromosome and application of a hybridization probe consisting of an individual member copy of a repetitive human DNA family. A linear map has been constructed of 19 marker DNA fragments and 5 immunological and biochemical markers on human chromosome 11, selected as a model chromosome for these studies. This approach appears to be widely applicable, is independent of cytogenetic analysis, promises to be capable of revealing the existence of rearrangements as well as deletions, appears to be amenable to further increase in resolving power, and offers potential application in various human genetic problems.
