The replication of ribosomal DNA in the macronucleus of Tetrahymena
Chromosoma, 1977The replication of extrachromosomal rDNA molecules from the macronucleus of Tetrahymena was studied by electron microscopy. Replication begins in the center of the palindromic molecule and proceeds by means of bidirectional fork movement toward the free ends of the molecule.

Ribosomal DNA in spores of Physarum polycephalum
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1978DNA was isolated from plasmodia, spores and newly hatched amoebae of the slime mould Physarum polycephalum. The DNA preparations were fractionated in CsCl gradients and each fraction hybridised to combined 19 S + 26 S rRNA. In all three DNA preparations hybridisation was found to be limited to satellite DNA (rho = 1.714 g/cm3) and at saturation was ...

Structure of ribosomal DNA in Physarum polycephalum
Journal of Molecular Biology, 1976Abstract The sequences coding for Physarum ribosomal RNA are localized on idependently replicating, linear DNA molecules of a discrete size, M r = 37 × 10 6 . Restriction endonucleases Eco RI and Hin dIII each cut ribosomal DNA into one large and two small fragments.

Ribosomal DNA Probes and Primers
1998Ribosomal DNA (rDNA) is the region of the genome coding for the RNA component of ribosomes. The ubiquity and conservation of rDNA sequences has made these DNA regions important tools for reconstructing phylogenetic relationships. In eukaryotes, rDNA sequences may be found in the nucleus and organelles.

Heterogeneity in Chinese hamster ribosomal DNA
Chromosoma, 1978A discrete heterogeneity has been detected in Chinese hamster ribosomal DNA after Eco R1 digestion of total DNA followed by a Southern transfer and hybridization with [125I]18S or [125I]28S ribosomal RNA. Digestion with Eco R1 produces three fragments, 4.3, 6.0 and 9.5 x 10(6) daltons respectively, which hybridize with 18S RNA.
