Inhibitors of ribonucleic acid synthesis in Saccharomyces cerevisiae: decay rate of messenger ribonucleic acid.
Daunomycin and ethidium bromide, two deoxyribonucleic acid-intercalating drugs, inhibit ribonucleic acid (RNA) and protein synthesis in Saccharomyces cerevisiae. Both agents rapidly curtail uptake of radioactive adenine, whereas the kinetics of radioactive leucine uptake after drug addition are consistent with translation of a pool of exponentially decaying messenger RNA. Messenger RNA half-lif...
متن کاملRate of synthesis and half-life of globin messenger ribonucleic acid. Rate of synthesis of globin messenger ribonucleic acid calculated from data of cell haemoglobin content.
By the use of the favoured models defining mRNA synthesis and half-life from the preceding paper (Hunt, 1974) and the known content of globin in a reticulocyte it is possible to estimate the absolute rate of mRNA and globin synthesis and the mRNA and globin content in each type of erythroid cell. The best model requires an mRNA-synthetic rate of 3000 molecules per h/cell. This rate compares fav...
متن کاملRelationship between sporulation-specific 20S ribonucleic acid and ribosomal ribonucleic acid processing in Saccharomyces cerevisiae.
The nature and properties of the 20S ribonucleic acid which accumulates only during the sporulation of Saccharomyces cerevisiae were examined. The 20S ribonucleic acid (RNA) has a base composition considerably different from ribosomal RNA species and is virtually unmethylated. The 20S RNA did, however, exhibit approximately 70% homology with 18S RNA by RNA-deoxyribonucleic acid filter hybridiza...
متن کاملNuclear deoxyribonucleic acid-dependent ribonucleic acid polymerases from Saccharomyces cerevisiae.
Two deoxyribonucleic acid (DNA)-dependent ribonucleic acid (RNA) polymerases (I, II) have been solubilized from isolated Saccharomyces cerevisiae nuclei. The enzymes can be separated by chromatography on O-diethylaminoethyl Sephadex. Both enzymes are active with high-molecular-weight nuclear yeast DNA, although RNA polymerase I has a higher affinity for polydeoxy-adenylic-thymidylic acid and RN...
متن کاملIdentification of an actin-like protein and of its messenger ribonucleic acid in Saccharomyces cerevisiae.
We have identified a yeast protein that resembles actins from other eucaryotes in its tight binding to pancreatic deoxyribonuclease I, its copolymerizaton with purified muscle actin, its one-dimensional peptide map, and its apparent polymerization into 7-nm filaments. The yeast actin-like protein yielded a single spot on two-dimensional polyacrylamide gel electrophoresis, suggesting that a sing...
