Membrane-bound ribonucleic acid synthesis in Escherichia coli infected with ribonucleic acid bacteriophage R23.
1. A cell membrane-DNA-RNA polymerase complex which contains virtually all of the RNA-synthetic capacity of the cell has been isolated from uninfected and R23-infected Escherichia coli. 2. Infection of E. coli by RNA bacteriophage R23 inhibits the RNA synthetic capacity of the membrane complex. In infected cells some of the RNA synthetic capacity is released from the membrane fraction. 3. The m...
متن کاملDegradation of Ribonucleic Acid in Mouse Fibroblasts Treated with Actinomycin
The cellular RNA content of mouse fibroblasts incubated with actinomycin decreases at a rate of about 1 to 1.5 per cent per hour, while DNA and protein content remain unchanged. This degradation affects nuclear and cytoplasmic RNA, ribosomal and soluble RNA. The breakdown products appear quantitatively in the acid-soluble fraction of the cells and the medium. Polynucleotides synthesized a short...
متن کاملEnzymatic 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 کاملThe Enzymatic Synthesis of Ribonucleic Acid. v. the Interaction of Ribonucleic Acid Polymerase with Nucleic Acids.
Numerous reports have been published on the properties and reaction mechanism of the highly purified enzyme preparations that catalyze the deoxyribonucleic acid-directed synthesis of ribonucleic acid (l-6). The various RNA polymerases tudied, although differing in some respects, show a remarkable similarity in their cofactor requirements, reaction kinetics, physical properties, and facility to ...
