嘌呤碱基

The basic concept is that the DNA bases, adenine, cytosine, guanine and thymine, could be distinguished in terms of their conductivity properties.

那个 基本概念是，DNA碱基，腺嘌呤，胞嘧啶，鸟嘌呤和胸腺嘧啶的，可区分的条件它们的导电性能。

In DNA, four different bases are found. Two of these, adenine and guanine , are double-ring structures called purines.

在DNA中，有四种不同的碱基，其中的两个为腺嘌呤和鸟嘌呤，即称为嘌呤的双环结构。

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。

Mainly includes the adenine, the guanine, the thymine and the cytosine 4 kind of basic groups.

主要含有腺嘌呤、鸟嘌呤、胸腺嘧啶和胞嘧啶4种碱基。

Members of the purine group include adenine and guanine, which are constituents of the nucleic acids, and certain plant alkaloids, e.g.

嘌呤基的成员包括腺嘌呤和鸟嘌呤，它们是核酸以及某些植物生物碱的成分，如咖啡因和可可碱。

Guanine A nitrogenous base found in DNA and RNA. Guanine has a pruine ring structure.

鸟嘌呤：是存在于 DNA 与 RNA 中的一种含氮碱基，具有一个嘌呤环结构。

The most abundant bases are cytosine, thiamine, and uracil and adenine and guanine.

最丰富的碱基是胞嘧啶，胸腺嘧啶，尿嘧啶，腺嘌呤和鸟嘌呤。

The basic group has five kinds, respectively be adenine, guanine, cytosine, thymine and uracil.

碱基有五种，分别为腺嘌呤、鸟嘌呤、胞嘧啶、胸腺嘧啶和尿嘧啶。

There are four bases, called adenine, thymine, guanine, and cytosine.

共有四个碱基：腺嘌呤、胸腺嘧啶、鸟嘌呤和胞嘧啶。

The influence of binding of cisplatin adducts on tautomeric equilibrium of guanine was investigated using quantum chemical method. The monoaqua adduct [Pt(NH3)2Cl(H2O)]＋and the diaqua adduct [Pt(NH3)2(H2O)2]2＋were chosen for coordination to the N(7) site of guanine tautomers.

使用量子化学MPW1PW方法，优化了顺铂键连到DNA碱基-鸟嘌呤及互变异构体N7形成的配合物的构型，同时用MP2方法计算其能量，以研究顺铂对鸟嘌呤互变异构作用的影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
