The transcription of DNA in chromatin by Escherichia coli RNA polymerase resembles that of isolated DNA in two important respects: the release of nascent RNA and reinitiation of RNA synthesis is dependent on the salt concentration, and RNA synthesis is markedly stimulated by the addition of ribosomes.
大肠杆菌RNA聚合酶对染色质中DNA的转录在两个重要方面类似于对分离DNA的转录:新生RNA的释放和RNA合成的重新起始取决于盐浓度,并且添加核糖体可显著刺激RNA合成。
