Uracil and fuzinoside may be the cardiotonic components of aconite roots.

从附子水溶液部分分离得到尿嘧啶、附子苷是附子中强心成分。

Technologies for determining methylation patterns in cancer cells, Methyl Light and COBRA, both of which were based on the deamination of methylated cytosines—which converts these cytosines to uracil residues—and identification of the converted sequence by analytical methods.

在上世纪80年代期间,研究的主要方法是PCR和克隆,两者都不涉及甲基化内容,因此很快就被弃用了。90年代,Laird开发了两类技术去检测肿瘤细胞中的甲基化模式,MethylLight和COBRA,两者都是以甲基化胞嘧啶的脱氨作用(将胞嘧啶转化为尿嘧啶残基)以及通过分析方法鉴定修改的序列为基础。

Uracil also can be introduced by hydrolytic deamination of cytosine which paired with guanine. Highly mutagenic dU:dG mispair may cause a C→T transition mutation upon replication if it was not repaired.

另一种可能则是由胞嘧啶(Cytosine; C)发生自发性或氧化脱胺反应而形成尿嘧啶与鸟粪嘌呤的配对错误。

RNA editase transforms or modifies the nucleotide of pre-RNA by deaminization, and hydrolytic deaminize C6 amino group of the adenosine at the specific RNA site, changing adenosine to inosine or changing cytosine to uracil,but inosine was recognized as guanine in mRNA.

RNA编辑酶以脱氨方式使得RNA特异位点的腺嘌呤脱氨转变为次黄嘌呤,或者是特异位点的胞嘧啶变为尿嘧啶,而次黄嘌呤在碱基配对时被识别为鸟嘌呤。

Two modified beacons containing of uracil and hypoxanthine have been used to validate the assay on purified proteins with success. However, while applying the assay to cell extracts, the results were interfered by non-specific nuclease activities.

我们分别设计其中含有尿嘧啶以及inosine的分子信号,以测定尿嘧啶-核酸醣解酶(uracil-DNA glycosylase)以及次黄嘌呤-核酸醣解酶(hypoxanthine-DNA glycosylase)的活性。

In the end, the effects of methylation on the properties of uracil and adenine-uracil base pair have been investigated.

最后,我们研究了甲基化对脲嘧啶单体以及腺嘌呤-脲嘧啶碱基对的影响情况。

Investigations on the influence of different biological surroundings on the structures and properties of the Uracil should be helpful in understanding the essence of Uracil.

它的发展及影响随着新理论的不断提出及高级计算方法的不断出现而逐渐加强。

It's initiated by uracil-DNA glycosylase, which removes the uracil, leaving an abasic site.

大肠杆菌中主要是利用碱基切除修复(base excision repair; BER)对DNA中的U进行修复。

Methyl-5-ethyl-2-thiouracil,m.p.211°,was prepared according to the direc- tions of Johnson and Baily.4-Methyl-5-ethyl-uracil,m.p.236°,was formed in a 81% yield from 4-methyl-5-ethyl-2-thiouracil by boiling the latter with an aqueous solution of monochloroacetic acid.4-Methyl-5-ethyl-uracil reacted with phosphorous oxychloride and phosphorous pentachloride,giving 4-methyl-5-ethyl-2,6-dichloropy- rimidine in a 79% yield.

14-甲基5-乙基-2,6-二氯代嘧啶曾用磷醯氯和五氯化磷与其相应的2,6-二羟基嘧啶作用制取。(2)4-甲基-5-乙基-2,6-二氯代嘧啶与醇钠作用,极易转变成4-甲基-5-乙基-2,6-二烷氧基嘧啶。(3)4-甲基-5-乙基-2,6-二甲氧基嘧啶和2-氧代-3,4-二甲基-5-乙基-6-甲氧基嘧啶在高温时重排成其稳定构型的的异构体:1,3,4-三甲基-5-乙基-2,6-二氧代嘧啶。

For the isolated Uracil, the shift of the appropriate hydrogen atoms can generate many different tautomers. Moreover, theoretical studies demonstrate that some tautomers of Uracil possibly result in the mispair of nucleic acid base pairs.

通过氢原子的转移,脲嘧啶可以产生许多互变异构体,而且研究表明它的一些互变异构形式可能会导致碱基的错配。
