using three cloned dna fragments from a 6.4-kb ( kilobase pair ) dna element repeated several thousand times in the human genome ( adams , j. w. , kaufman , r. e. , kretschmer , p. j. , harrison , m. and nienhuis , a. w. ( 1980 ) nucleic acids res . 8 , 6113-6128 ) and dna/rna hybridization , we show that transcripts homologous to this dna family exist in total cellular rna from human blood cells and from a mouse-human hybrid cell line with one human chromosome , the x .
