The synthesis of messenger RNA without protein synthesis

摘要: Escherichia coli , deficient in the ability to synthesize thymine, uracil and an amino acid, a small fraction of their normal RNA from absence thymine acid. The synthesis even this is inhibited by concomitant DNA synthesis. Most (75%) made appears on ribosomes can be degraded these structures presence inorganic phosphate. When synthesized inducer β -galactosidase, permit rapid amount enzyme apparent inducer. These observations are consistent with hypothesis that essential acid protein largely messenger RNA.
