Summary
The quantity of ribosomal RNA genes and the rate of ribosomal RNA synthesis has been studied in established cell lines of Drosophila melanogaster with diploid, polyploid and hemizygous karyotypes and in larval diploid cells carrying 1, 2, 3 or 4 nucleolar organizer regions. The rate of rRNA synthesis has been shown to depend on the number of sex chromosomes rather than ribosomal genes or nucleolar organizers.
