Hybridization of plant ribosomal RNA to DNA: the isolation of a DNA component rich in ribosomal RNA cistrons.
Several studies of artificial hybridization between ribosomalRNA and homologous and heterologous DNA's from animal and bacterial sources have been reported. These studies indicate that there is a multiplicity of cistrons coding for ribosomal RNA,1-8 that these cistrons are located at the nucleolar organizer region of higher organisms,2' and that nucleotide sequences of ribosomal RNA tend to be ...
متن کاملCharacterization of cytoplasmic and nuclear genomes in the colorless alga Polytoma. III. Ribosomal RNA cistrons of the nucleus and leucoplast
The colorless alga Polytoma obtusum has been found to possess leucoplasts, and two kinds of ribosomes with sedimentation values of 73S and 79S. The ribosomal RNA (rRNA) of the 73S but not the 79S ribosomes was shown to hybridize with the leucoplast DNA (rho - 1.682 g/ml). Nuclear DNA of Polytoma (rho = 1.711) showed specific hybridization with rRNA from the 79S ribosomes. Saturation hybridizati...
متن کاملThe number, physical organization and transcription of ribosomal RNA cistrons in an archaebacterium: Halobacterium halobium.
Because it is now clear that archaebacteria may be as distinct from eubacteria as either group is from eukaryotic cells, and because a specifically archaebacterial ancestry has been proposed for the nuclear-cytoplasmic component of eukaryotic cells, we undertook to characterize, for the first time, the ribosomal RNA cistrons of an archaebacterium (Halobacterium halobium). We found these cistron...
متن کاملCisplatin Targeting of Bacterial Ribosomal RNA Hairpins
Cisplatin is a clinically important chemotherapeutic agent known to target purine bases in nucleic acids. In addition to major deoxyribonucleic acid (DNA) intrastrand cross-links, cisplatin also forms stable adducts with many types of ribonucleic acid (RNA) including siRNA, spliceosomal RNAs, tRNA, and rRNA. All of these RNAs play vital roles in the cell, such as catalysis of protein synthesis ...
متن کاملChromosomal location of ribosomal protein cistrons determined by intergeneric bacterial mating.
Intergeneric mating between Escherichia coli and Salmonella typhosa was used to locate at least three 30S ribosomal proteins near the streptomycin locus in the region of 54 to 66 min of the E. coli map. This procedure utilizes differences in the electrophoretic patterns of 30S ribosomal protein of the parents. The results show that cistrons for 30S proteins of E. coli can replace those of S. ty...
