Localization of chromosomal DNA sequences homologous to ribosomal gene type I insertion DNA in Drosophila melanogaster.

E S Cantú, H Gay.   

Abstract

Chromosomal sites which have DNA homology to the 1 kb (kilobase pair) BamHI restrictable fragment of the 5 kb type I insertion present in many ribosomal genes in Drosophila melanogaster, were identified by using in situ hybridization and autoradiography. XX and XY complements of polytene chromosomes showed the nucleolus and chromocenter to be heavily labeled. Of the light label over euchromatic regions, the 102C band of chromosome 4 labeled particularly intensely. In mitotic XX and XY complements, the NORs (nucleolus organizer regions) of both sex chromosomes labeled as did the centromeric heterochromatin of autosomes. Label also appeared less frequently over telomeric and euchromatic regions.
