title: Inhibition of deoxyribonucleic acid replication in Bacillus brevis by ribonucleic acid polymerase inhibitors.
abstract: The incorporation of [3H]thymidine into deoxyribonucleic acid by exponentially growing cells of Bacillus brevis was inhibited by streptolydigin and rifampin in the same concentration range in which these drugs inhibit ribonucleic acid synthesis. Complete inhibition occurred within one-third generation time after drug addition, suggesting an effect on deoxyribonucleic acid chain elongation.
