Indirect evidence for the presence of Ribonucleic acid in vesicular stomatitis Virions

Conservation of Ribosomal and Messenger Ribonucleic Acid Cistrons in Bacillus Species.

Doi, Roy H. (Syracuse University, Syracuse, N.Y.), and Richard T. Igarashi. Conservation of ribosomal and messenger ribonucleic acid cistrons in Bacillus species. J. Bacteriol. 90:384-390. 1965.-Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) fractions from various Bacillus species were tested for interspecies DNA-RNA hybrid formation. DNA preparations from B. subtilis, B. cereus, B. meg...

Stability of ribosomal and transfer ribonucleic acid in Escherichia coli B/r after treatment with ethylenedinitrilotetraacetic acid and rifampicin.

A short treatment with ethylenedinitrilotetraacetic acid to permeabilize bacteria for various antibiotics or treatment with the ribonucleic acid (RNA) synthesis inhibitor rifampin causes a slow degradation of 50S and 30S ribosomal particles and of the corresponding 23S and 16S ribosomal RNA species (about 25 percent in 1 h). The effects are additive such that the decay is about 50 percent/h if ...

Transfer ribonucleic acid nucleotidyltransferase and transfer ribonucleic acid in Sendai virions.

Sendai virions contain both transfer ribonucleic acid (tRNA) nucleotidyltransferase and its substrate, tRNA missing its CCA-OH end.

Cistrons Among Yeast Chromosomes

High-molecular-weight deoxyribonucleic acid (DNA) of Saccharomyces carlsbergensis has been fractionated by sucrose density gradient centrifugation. The main DNA fraction has an average molecular weight of about 500 x 106. A major fraction of the DNA molecules containing sequences homologous to ribosomal ribonucleic acid (RNA) sediments as material of this molecular weight. The remainder sedimen...
