Thedideoxynucleotides act as chain terminators since they have no 3'-OHgroup on the deoxyribose which is needed by the synthesis step.

双脱氧核苷酸在脱氧核糖上没有聚合酶延伸链所需要的3'－OH基团，所以可被用作链终止试剂。从得到的PAGE胶上可以读出我们需要的序列。

The dideoxynucleotides act as chain terminators since they have no 3'-OH group on the deoxyribose which is needed by the synthesis step.

双脱氧核苷酸在脱氧核糖上没有聚合酶延伸链所需要的3'－ OH 基团，所以可被用作链终止试剂。从得到的 PAGE 胶上可以读出我们需要的序列。

"Each consists of a molecule of a five-carbon sugar (ribose in RNA, deoxyribose in DNA) and a nitrogen-containing base, either a purine or a pyrimidine."

由一分子五碳糖(核糖核酸中的核糖、去氧核糖核酸中的去氧核糖)与一含氮的嘌呤或嘧啶相连而成。

A nucleoside, C10H14N2O5, composed of thymine and deoxyribose.

在细胞的新陈代谢中一种由二磷酸腺苷合成三磷酸腺苷的酶促过程。

Peptide nucleic acid is a kind of new nucleic acid mimic invented in the early 1990s', in which the deoxyribose phosphate backbone has been replaced by a pseudo-peptide polymer to which the nucleobases are linked. PNA is uncharged, highly stable in chemical and biological environments, and binds complementary DNA and RNA targets with remarkably high affirnity and specificity.

肽核酸是二十世纪九十年代初合成的一种全新的核酸类似物，它以多肽骨架完全替代DNA中的脱氧核糖磷酸二酯键的骨架，呈电中性，具有极高的生物和化学稳定性、极强的核酸结合能力和特异性，在分子生物学的许多方面得到广泛应用。

The Raman spectral bands indicated that the damage of the heating on the DNA conformation is limited below the melting point. The damage of the DNA molecular structure increased with a rise in temperature above the melting point. The damage was first obversed in adenine and deoxyribose.

研究结果表明，在熔融温度以下热处理对DNA构象的影响是轻微的，在熔融温度以上则随温度的升高，对DNA分子结构的影响及破坏也逐渐加剧，首先受影响的是腺嘌呤和脱氧核糖。

In DNA the corresponding sugar is the closely related deoxyribose. A ribose molecule combined with adenine, guanine, cytosine, or uracil forms a nucleoside; adding a phosphate group forms a nucleotide.

去氧核糖核酸中相应的糖类和去氧核糖密切相关核糖分子和腺嘌呤、鸟嘌呤、胞嘧啶或尿嘧啶形成核；再加上磷酸盐和磷酸酯便成为核。

Heating, ethanol precipitation, and ion-exchange chromatographies had been carried out to isolate the protein with specific stimulating activity from newborn calf liver, and [(3)H]thymidine deoxyribose/bromodeoxyuridine incorporation and carboxyfluorescein diacetate succinimidyl ester-based proliferation assay to determine the bioactivity in vitro and in vivo.

通过用加热、乙醇沉淀、离子交换层析等方法来分离新生小牛肝脏中含有特殊刺激活性的蛋白和用胸嘧啶脱氧核糖/溴脱氧尿苷联合羧基荧光素双乙酸钠琥珀酸酯为基础的扩增分析其体内和体外的生物活性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
