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 Streptomyces antibioticus: stable ribonucleic acid species synthesized by young and old cells.
In studies of RNA synthesis by intact cells and cell-free extracts of Streptomyces antibioticus, it has been found that 48 hr cells (producing actinomycin) and cell-free extracts are less efficient than 12 hr cells (not producing actinomycin) and extracts in the synthesis of RNA. Analysis of the products of "in viva" and "in vitro" RNA synthesis by sucrose gradient cent trifugation reveals that...
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 کاملEnzymatic Synthesis of Ribonucleic Acid. Iv. the Deoxyribonucleic Acid-directed Synthesis of Complementary Cytoplasmic Ribonucleic Acid Components.
The ribonucleic acid product formed by ribonucleic acid polymerase resembles its deoxyribonucleic acid template in base composition and in base sequence (l-6). The reaction in vitro results in the synthesis of RNA chains which are complementary to both DNA strands (6). Evidence for this originates from the formation of highly ordered RNA structures when the RNA polymerase product is annealed wi...
متن کاملRibonucleic acid synthesis during fungal spore germination.
Spores of several fungi were examined in an effort to understand the role of RNA in the biochemical events occurring early in germination. RNA synthesis appeared to be an essential requirement for germination in Neurospora crassa and Aspergillus nidulans but not in Alternaria solani and Peronospora tabacina. Gross changes in the relative amounts of the various molecular species of RNA were not ...
