脱氧核糖核酸

CpG islands often occur at transcriptionally active DNA.

CpG island 通常出现在随时准备好转录或转译的脱氧核糖核酸中可以观察到

"The fact that a basic sugar so directly linked to RNA is common makes you think the basic ingredients for life are out there," Viti said. They're not just on Earth.

& &事实上，一种跟脱氧核糖核酸直接相关的基本糖类普遍存在，不由得使你认为：生命的基本组成成分就存在于那里，&维蒂说，&它们不仅仅存在于地球上。

Results The endothelial cell and fibroblast of valves and vessel walls in experimental group were completely decellularized, no cell fragments were retained within the matrix scaffold; collagen fiber and elastin fiber had been preserved with intact structure and wavily arrayed; deoxyribonucleic acid content of valves and vessel walls in experimental group were decreased by 97.58%, 97.25% compared with that of control group.

结果 实验组瓣膜及血管壁中内皮细胞、成纤维细胞去除完全，无细胞核碎片；瓣膜及血管壁胶原纤维和弹力纤维呈波浪状排列、整齐，结构完整；瓣膜、血管壁的基因组脱氧核糖核酸含量分别较对照组下降97.58％和97.25％。

Recently, rat, zebrafish, and Xenopus have been added, and we anticipate arraying cDNA libraries from additional species over time.

近来大鼠，斑马鱼和非洲有爪水生蛙的研究陆续加入，我们预期排列新加入研究物种的互补脱氧核糖核酸数据库也会陆续产生。

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。

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。

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。

For now, the scientists have determined that miR-133b likely works in a negative feedback loop with a transcription factor called Pitx3: during the course of its work, Pitx3 transcribes miR-133b from the DNA in the neurons.

现在，科学家们已经确定空间站- 133b工程可能在负反馈回路与转录因子称为pitx3 ：在工作过程中，转录pitx3传奇- 133b从脱氧核糖核酸的神经。

A chromosome is a piece of DNA, deoxyribonucleic acid, in the nucleus of a cell.

染色体是脱氧核糖核酸的一部分，在一个细胞的胞核中。

DNA is stored in the nucleus of a cell.

脱氧核糖核酸储存于细胞的细胞核里。

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。
