Control of 5s Rna Synthesis during Early Development of Anucleolate and Partial Nucleolate Mutants of Xenopus Laevis

Ribosomes of all eukaryotes contain a single molecule of 5S, 18S, and 28S RNA. In the frog Xenopus laevis the genes which code for 18S and 28S RNA are located in the nucleolar organizer, but these genes are not linked to the 5S RNA genes. Therefore the synthesis of the three ribosomal RNAs provides a model system for studying interchromosomal aspects of… (More)
