摘要：

The 5S RNA gene content of polyploid cells of the ovary of Drosophila melanogaster has been compared in animals with two or three gene clusters. The amount of 5S RNA genes is exactly proportional to the number of gene clusters as determined by DNA-RNA filter hybridization. In contrast, the number of rDNA genes in endomitotic cells remains constant regardless of different numbers of nucleolus organizer regions (Spear, 1974). © 1979 Springer-Verlag.
