title: Chromosomal arrangement of heat shock locus 2-48B in Drosophila hydei.
abstract: cDNA, copied from nuclear RNA isolated from heat shocked Drosophila hydei cells, has been cloned. From this collection of clones a clone, N09-15, with a 450 bp insert has been isolated that hybridizes in situ to the heat shock locus-2-48B of Drosophila hydei. The N09-15 sequence is present in two different genomic arrangements, as shown by restriction mapping, in our wild type D. hydei population. These genomic arrangements are allelic. Both alleles contain multiple copies of the N09-15 sequence but differ in their lengths and in the distribution of Msp I and Taq I sites.
