脱氧

Each nucleotide subunit consists of three components: a phosphate group, a deoxyribose sugar ring, and a nucleobase.

每个核苷酸亚基包括三个组成部分：一个磷酸基团，一个脱氧核糖糖环，和

In the contrast, UVA damaged the deoxyribose and base pairs more seriously: some moieties were destroyed and some base pairs were modified.

UVA对脱氧核糖和碱基的损伤相对来说要严重些，一些基团结构被破坏，部分碱基对受到修饰。

This exposes the aldehyde groups of deoxyribose. The tissue is then soaked in Schiff ' s reagent: the development of a magenta color indicates the location of DNA.

从而暴露出脱氧核糖的醛基，然后将其放入 Schiff ' s 试剂中，紫红色部分显示 DNA 的存在部位。

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acid is a kind of new nucleic acid mimic invented in the early 1990s', in which the deoxyribose phosphate backbone has been replaced by a pseudo-peptide polymer to which the nucleobases are linked.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。

Then, is the life there also in the form of DNA, deoxyribonucleic acid ?

然且， 那里的生命是以脱氧核糖核酸DNA的形式出现的吗？

He was able to analyze this further and discovered an acid component which he called deoxyribonucleic acid.

他还进一步分析了和这发现这种酸化合物而他把这较为脱氧核糖酸。

DNA is the short form of deoxyribonucleic acid .

DNA是脱氧核糖核酸的缩写形式。

Deoxyribonucleic acid is an important chemical substance in our life process.

脱氧核糖核酸是生命过程中的重要化学物质。

It is known that they are strands of deoxyribonucleic acid, the hereditary material of the cell.

已知它们为脱氧核糖核酸链，是细胞的遗传物质。

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。
