Development of Bacteriophage Alpha II. Dependence on the Host Ribonucleic Acid Polymerase

RESUMO
Measurements of ribonucleic acid (RNA) synthesis using 14C-uracil uptake in rifampin-sensitive and rifampin-resistant strains of Bacillus megatherium were carried out after infection of the bacteria with bacteriophage α. Phage development was inhibited in the former but not the latter strain, showing that α phage development is dependent on the bacterial host RNA polymerase. This dependence exists at all times during eclipse. RNA polymerase extracts showed the same in vitro rifampin sensitivity as the corresponding bacterial strains.
