Like DNA itself, the story has two entwining strands. As researchers deprived of public funds turn to commercial companies to pay for their research, those companies seek to protect their intellectual property for their shareholders' benefit.

正如脱氧核糖核酸本身一样，这种情况也具有两股缠绕的链因为研究人员不能取得公共基金而转向商业公司，并由这些公司来资助他们的研究，那些公司则为了他们股东的利益力求保护他们的知识产权。

Objective: Design and synthesize the oligodeoxynucleotides containing unm- ethylated CpG dinucleotides to screen out the optimal CpG-ODN that could markedly enhance the immune function of cord blood mononuclear cells in health newborns. Moreover, observe the action of CpG-1826 (5'-TCCATGACGTTC CTGACGTT-3') as the immune adjuvant of the hepatitis B vaccine on the pregnant mice and their neonatal mice.

目的：设计并合成含非甲基化胞嘧啶和鸟嘌呤二核苷酸的寡聚脱氧核糖核苷酸，以期筛选出对新生儿脐血单个核细胞免疫刺激作用较强的CpG-ODN；观察不同剂量CPG-1826(5'-TCCATGACGTTCCTGACGTT-3')辅助乙肝疫苗免疫孕鼠及仔鼠的作用。

Scientists studying the DNA of Neanderthals say they can find no evidence that this ancient species ever interbred with modern humans.

研究尼安德特人的脱氧核糖核酸的科学家说他们能没有找到证据，曾经这种古代物种interbred与现代人类。

The specific inhibitor of DNA methylation that is available currently is 5-Aza-2'-deoxycytidine (5Aza-dc), which forms a covalent bond with the DNA methyltransferase, thus, limiting the number of free DMT molecules for methylating DNA and then decreasing its biology activity.

目前研究较多的甲基化抑制剂是胞苷类似物5-氮杂-2'-脱氧胞苷(5-Aza-2'-deoxycytidine， 5Aza-dc)。5Aza-dc的作用机制是与DNA甲基转移酶共价结合，降低酶的生物活性。

Among all the moieties of DNA, the pirimidine bases and deoxyribose may be the first to be damaged by UV.

我们还发现在DNA的所有基团中，最先受到损伤的可能是嘧啶碱基和脱氧核糖。

Enzyme that polymerizes deoxyribonucleotides to make DNA.

将脱氧核糖核苷酸聚合形成DNA的酶。

METHODS: In mobilization group (M, n=10), granulocyte-colony stimulating factor (30 μg·kg-1·d-1) was injected subcutaneously 3 hours after MI and every 24 hours for 5 days. On the 5th day, the BMCs from 10 mL peripheral blood were labeled with bromodeoxyuridine for 24-48 hours, then reinjected intravenously. In transplantation group (T, n=10), BMCs transplantation was performed 5-7 days after MI.

将30只新西兰兔采用结扎前降支的方法复制心肌梗死模型，随机分为动员组、移植组和对照组，动员组（n=10）心梗后3 h开始皮下注射粒细胞集落刺激因子30 μg·kg-1·d-1，连续使用5 d，第5 d抽取静脉血约10 mL，分离单个核细胞用5-溴脱氧尿嘧啶核苷标记后，经静脉注入动物体内。

An online preconcentration method, electrokinetic supercharging was used for the enrichment of DNA fragments based on microchip electrophoresis.

采用超负荷电动供给(electrokinetic supercharging， EKS)预浓缩技术，在微芯片电泳上对脱氧核糖核酸片段进行浓缩和分离。

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。
