    • Provided are novel nucleotides, nucleoside, and their derivatives described herein, that can be used in DNA sequencing technology and other types of DNA analysis. In one embodiment, the nucleotide or nucleoside with an unprotected 3′-OH group is derivatized at the nucleobase to include a fluorescent dye attached via a linker to a photocleavable terminating group. The photocleavable-fluorescent group is designed to terminate DNA synthesis as well as be cleaved so that DNA oligomers can be sequenced efficiently in a parallel format. The design of such rapidly cleavable fluorescent groups on nucleotides and nucleosides can enhance the speed and accuracy of sequencing of large oligomers of DNA in parallel, to allow rapid whole genome sequencing, and the identification of polymorphisms and other valuable genetic information, as well as allowing further manipulation and analysis of nucleic acid molecules in their native state following cleavage of the fluorescent group.
    • 提供本文所述的新型核苷酸,核苷及其衍生物,其可用于DNA测序技术和其他类型的DNA分析。 在一个实施方案中,具有未被保护的3'-OH基团的核苷酸或核苷酸在核碱基处被衍生化,以包括经由连接体连接至可光切割终止基团的荧光染料。 可光致透照荧光基团被设计用于终止DNA合成以及被切割,使得DNA寡聚体可以以并行格式有效排序。 在核苷酸和核苷上的快速切割荧光基团的设计可以提高DNA大尺寸寡聚体平行测序的速度和准确性,以便快速进行全基因组测序,以及鉴定多态性和其他有价值的遗传信息,以及允许 进一步操纵和分析在荧光基团裂解后的天然状态的核酸分子。
