Enzymatic Synthesis of Ribonucleic Acid
The discovery of enzymes which catalyze the deoxyribonucleic acid-dependent synthesis of ribopolynucleotides (l-6) stimulated an immediate inquiry into the role played by DNA in thisunique reaction. The speculation that DNA might serve as a template for the polymerization of ribonucleotides into a complementary ribonucleic acid molecule was confirmed by studies from a number of different groups...
متن کاملRibonucleic acid synthesis in tumor homogenates.
Ochoa and his collaborators (6) have shown that cell-free extracts of certain bacteria can be used to accomplish the net synthesis of polynucleotides resembling ribonucleic acid (RNA)1 from purine and pyrimidine nucleoside diphosphates. The net synthesis of RNA by cell-free prepara tions from animal tissues has not been reported. However, renewal or turnover of RNA components in preparations fr...
متن کاملRole of ribonucleic acid synthesis in replication of deoxyribonucleic acid.
An experiment previously interpreted to show a ribonucleic acid requirement for propagation of deoxyribonucleic replication is reexamined and the earlier interpretation is shown to be incorrect.
متن کاملRole of isoleucyl-transfer ribonucleic acid synthetase in ribonucleic acid synthesis and enzyme repression in yeast.
Temperature-sensitive mutations in the isoleucyl-transfer ribonucleic acid (tRNA) synthetase of yeast, ilS(-)1-1 and ilS(-)1-2, were used to examine the role of aminoacyl-tRNA synthetase enzymes in the regulation of ribonucleic acid (RNA) synthesis and enzyme synthesis in a eucaryotic organism. At the permissive temperature, 70 to 100% of the intracellular isoleucyl-tRNA was charged in mutants ...
متن کاملFlagellar synthesis in Salmonella typhimurium: requirement for ribonucleic acid synthesis.
The micro-complement-fixation assay has been demonstrated to be a sensitive assay for flagella which occur in nanogram amounts. By use of this assay, it was found that flagellar synthesis occurs during starvation of Salmonella typhimurium for tryptophan, an amino acid not present in flagellar protein. Under these conditions net ribonucleic acid (RNA) synthesis was reduced to approximately 10% o...
