Abstract excerpt
Extreme changes in the proportions of the rDNA intergenic spacers (IGSs) have previously been demonstrated by us in the X-chromosomal rDNA array of the Drosophila melanogaster mutant sc8, where nearly all IGSs were found to be reduced in size. We have cloned different structural variants of the X...
