this region was isolated using a deficiency extending from the previously cloned heat-shock puff sequences at 87a7 to a large transposable element containing the loci white and roughest.fb-nof , a 7.5 kb element with partial homology to a family of inverted repeat sequences ( potter et al. , 1980 ) , is found very near the deficiency breakpoint , and is followed by dna originating from the white locus region .
