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

Amounts of chromosomal DNA were estimated for Feulgen-stained, ovarian cells from flies carrying certain mutant alleles of the otu (ovarian tumor) gene. Epithelial sheath cells and lumen cells were found to contain the diploid (2C) amount of DNA and therefore served as internal, cytophotometric stan
The genes coding for 5S RNA in barley were cloned, sequenced, and their cluster was assigned to chromosome 2 using wheat-barley chromosome addition lines. High-resolution gel-electrophoresis of DNA and subsequent hybridization revealed new details of the organization of 5S DNA both in wheat and barl
Episomes carrying limited regions of the chromosome where 5S RNA genes have previously been located are described. The DNA purified from each of these episomes contains one gene per molecule for each of the three ribosomal RNA species as shown by hybridization experiments.
