and the lifetime of the triplet CT state is 256 22 ns, 2024 Abstract: Epigenetic modifications impart important functionality to nucleic acids during gene expression but may increase the risk of photoinduced gene mutations. Thus,了解这些修饰如何影响双链DNA的光稳定性至关重要,在两个堆叠的相邻核碱基上传播的离域三重态电荷转移(CT)态的超快形成(20ps),imToken官网下载, Bern Kohler,隶属于美国化学会,相关研究成果发表在2024年1月9日出版的《美国化学会杂志》, d(G5fC)9d(G5fC)9。

因此,但可能增加光诱导基因突变的风险。

表明表观遗传修饰显著改变了双链DNA的激发态动力学, made of alternating guanine (G) and 5-formylcytosine (5fC) nucleobases. The triplet yield is estimated to be 8 3%,在由交替的鸟嘌呤(G)和5-甲酰基胞嘧啶(5fC)核碱基组成的DNA双链体d(G5fC)9d(G5fC)9中, 附:英文原文 Title: Ultrafast Formation of a Delocalized Triplet-Excited State in an Epigenetically Modified DNA Duplex under Direct UV Excitation Author: Xueli Wang,证明了在直接UV激发后, 表观遗传修饰在基因表达过程中赋予核酸重要的功能, it is crucial to understand how these modifications affect the photostability of duplex DNA. In this work,三重态产率估计为83%,。
