Abstract

The effect of phenethyl alcohol (PEA) on deoxyribonucleic acid (DNA)-membrane attachment was examined by means of the "M-band" technique of Tremblay, Daniels, and Schaechter. The results of this work indicate that no significant release of DNA from the membrane could be detected after treatment with 0.25% PEA, a concentration previously shown to prevent reinitiation of DNA replication. However, concentrations of 0.5% PEA and greater, which stop DNA replication immediately, appear to release 25 to 80% of the DNA from the membrane.

摘要

采用特伦布莱、丹尼尔斯和谢克特的“M带”技术,研究了苯乙醇(PEA)对脱氧核糖核酸(DNA)与膜附着的影响。这项研究结果表明,用0.25%的PEA处理后,未检测到DNA从膜上有明显释放,先前已表明该浓度可阻止DNA复制重新起始。然而,0.5%及更高浓度的PEA会立即停止DNA复制,似乎能使25%至80%的DNA从膜上释放出来。
