[High interindividual polymorphism in restriction fragment length and copy number of the TURI family of moderate human DNA repetitions].

A human DNA library has been searched for moderate repetitive sequences. Southern's blot analysis of one of the selected clones, which we have termed pTURI-6, has shown a high interindividual restriction fragment length and copy polymorphism. TURI-6 clone can serve as an efficient molecular marker for the identification of interindividual distinctions.
