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 کاملEffect of the "ribonucleic acid control" locus in Escherichia coli on T4 bacteriophage-specific ribonucleic acid synthesis.
Amino acid control of ribonucleic acid (RNA) synthesis in bacteria is known to be governed genetically by the rel locus. We investigated whether the rel gene of the host would also exert its effect on the regulation of phage-specific RNA synthesis in T4 phage-infected Escherichia coli cells. Since T-even phage infection completely shuts off host macromolecular synthesis, phage RNA synthesis cou...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
