Labeled cytosine, adenine, and guanine are rapidly incorporated by E. coli. A fraction of the radioactivity passes directly into RNA with very little delay. The remainder enters a pool before being incorporated into RNA. The fractions entering the pool and the time constants for equilibration of the specific activity of the pool are widely different for the four RNA bases.
标记的胞嘧啶、腺嘌呤和鸟嘌呤能被大肠杆菌迅速掺入。一部分放射性物质几乎没有延迟就直接进入RNA。其余部分在掺入RNA之前进入一个池。四种RNA碱基进入池的部分以及池比活平衡的时间常数差异很大。
