胸腺嘧啶

Adenine and guanine are purines and cytosine and thymine are pyrimidines.

腺嘌呤和鸟嘌呤是嘌呤和胞嘧啶和胸腺嘧啶是嘧啶。

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

The DFT (B3LYP/6-31 + G) method was used to study the relative stabilities and probable proton transfer in isolated and monohydrated 2,4-dithiothymine molecules in gas phase. The effects of water on relative stabilities and the rate of the proton transfer were analysed. The results indicate that only one tautomer for 2,4-dithiothymine can exist in gas phase.

采用密度泛函方法在B3LYP/6-31+G水平上研究了2，4-二硫基胸腺嘧啶孤立分子和水合物的异构体的相对稳定性和可能的质子迁移反应，分析了水分子的参与对 2，4-二硫基胸腺嘧啶异构体的相对稳定性和质子迁移速率的影响。

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。

"One of the purines or pyrimidines (cystosine, thymine, and uracil ) that occurs attached to the sugar component of DNa or RNa."

嘌呤或嘧啶(胸嘧啶、胸腺嘧啶和尿嘧啶)的一种，附着在脱氧核糖核酸或核糖核酸的糖分子上。

Three kinds of fluorescence polymer with the structure of acridine yellow were synthesized and the sensor for measuring nucleic acid was also fabricated.

论文第三部分开展了以荧光高分子为敏感试剂的新型光化学传感器载体研究，合成了N，N-二甲氨基对苯甲醛缩醛类聚合物，考察了苯环上不同取代基对荧光性能的影响，研究了该类敏感膜对乳酸、尿嘧啶、胸腺嘧啶和腺嘌呤的响应性能；合成了三种具有吖啶黄结构的荧光高分子，制成了测定核酸的传感器。

This kind of configuration suits the multi-nucleotide chain's purine pyrimidine alternate area. in 1989, the American scientists with scanning tunnel electron microscope law visual observation double helix DNA double helix DNA ︰ in 1952, Austrian lineage US biology chemist Zha Qiefu (E.chargaff,1905-) have determined in DNA 4 kind of basic group content, the discovery gland fat ling and thymine quantity are equal, the bird fat ling and cytosine quantity is equal.

这种构型适合多核苷酸链的嘌呤嘧啶交替区。1989年，美国科学家用扫描隧道电镜法直接观察到双螺旋DNA 双螺旋DNA︰1952年，奥地利裔美国生物化学家查伽夫（E.chargaff，1905—）测定了DNA中4种碱基的含量，发现其中腺膘呤与胸腺嘧啶的数量相等，鸟膘呤与胞嘧啶的数量相等。

Thus, nucleotides in DNA or RNA are typically called 'bases'; consequently they are commonly referred to simply by their purine or pyrimidine original base components adenine, cytosine, guanine, thymine.

因此，核苷酸的DNA或RNA通常是所谓的'基地'；因此，他们通常被称为只要他们嘌呤或嘧啶在原有的基础上组成部分腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶。

Nucleosides are compounds composed of a purine or pyrimidine base (usually adenine, cytosine, guanine, thymine, uracil) linked to either a ribose or a deoxyribose sugar.

核苷是由嘌呤基，嘧啶基(通常是腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶，尿嘧啶)与核糖或脱氧核糖相连而组成的化合物。

One of the purines or pyrimidines that occurs attached to the sugar component of DNA or RNA.

碱基嘌呤或嘧啶（胸嘧啶、胸腺嘧啶和尿嘧啶）的一种，附着在脱氧核糖核酸或核糖核酸的糖分子上
