DNA is a type of nucleic acid.

Decades before Watson and Crick were at work, Miescher was the first to identify what would become known as deoxyribonucleic acid or DNA.

在沃森与克里克工作的几十前，Miescher 第一个确定了后来被称为氧核糖核酸或 DNA 的东西。

And in case you didn't know, DNA is short for deoxyribonucleic acid – this is a substance in the cells of animals and plants that contains genetic information.

以防你不知道，DNA是氧核糖核酸的简称，它是动植物细胞内承载遗传信息的物质。

Muscle contraction, transporting molecules throughout the body, synthesizing DNA, etc.

It is the party animal of the atomic world, latching on to many other atoms (including itself) and holding tight, forming molecular conga lines of hearty robustness-the very trick of nature necessary to build proteins and DNA.

它是元素世界的交际花，缠住许多别的原子（包括自己），紧紧搂住不放，结成了称心如意而又极为牢固的分子康茄舞伴——大自然创建蛋白质和DNA（氧核糖核酸）的奥秘就在这里。

It was here in 1953 that Francis Crick charged in, interrupting lunchtime service, to announce that he and James Watson had " discovered the secret of life" . How DNA carries genetic information.

1953 ，弗朗西斯·克里克就是闯进这里，打断了午餐服务，宣布他和詹姆斯·沃森 “发现了生命的秘密”即氧核糖核酸如何携带遗传信息。

The search for the two black boxes was completed within seven days, with identification and DNA verification of all the passengers lost in the crash completed in eight days.

对两个黑匣子的搜寻在七天内完成，对坠机中所有乘客的身份和 DNA （氧核糖核酸，可辨别人的身份）验证在八天内完成。

Deep within the genetic heart of all our cells are telomeres, or repeating segments of noncoding DNA that live at the ends of the chromosomes.

在我们所有细胞的基因核心深处是端粒，即生活在染色体末端的非编码氧核糖核酸的重复片段。

So, it means that your gene, your DNA can mutate, and that could make, for example, the shape of the organism change to abnormal shapes.

所以，这意味着你的基因，你的氧核糖核酸可以变异，这可能会使生物的形状变得异常。

And so Cas9 can surf along the genes, the DNA bases in the genome, until it finds the perfect match for its guide RNA.

所以 Cas9 可以沿着基因，基因组中的氧核糖核酸碱基，直到找到与其指导核糖核酸的完美匹配。

The entire genetic code of every UK Biobank volunteer has been sequenced, so scientists can analyse DNA alongside images of the brain and body.

每位英国生物样本库中志愿者的基因编码都已被测序，这样科学家就可以在分析大脑与身体扫描图像的同时分析氧核糖核酸。

Specifically, folic acid is important for making red blood cells, and thymine and cytosine, two of the four bases that make up DNA.

具体来说，叶酸对制造红细胞很重要，胸腺嘧啶和胞嘧啶是构成氧核糖核酸的四种碱基中的两种。

Those amino acids then get reassembled using anabolic reactions into your very own, but somewhat different, proteins, as defined by your DNA.

然后这些氨基酸通过成代谢反应重组成你自己的，但有些不同的蛋白质，由你的氧核糖核酸定义。

Our understanding of deoxyribonucleic acid, or DNA, has grown enormously since its discovery in the 19th century.

自从 19 世纪发现氧核糖核酸以来，我们对它的了解有了长足的发展。

That means they contain ingredients like avobenzone and octinoxate that absorb UV rays to stop them from damaging the DNA in your skin.

它们含有像阿伏苯宗和辛氧酸盐这样的成分，可以吸收紫外线，防止其损害皮肤中的氧核糖核酸。

That's right. This is because the UK has become the first country to approve laws allowing the creation of babies with DNA from three people!

是的。这是因为英国第一个通过了允许从三个人身上获取DNA（氧核糖核酸）孕育婴儿的法律！

Wait! But isn't DNA the building blocks of life?

等等。但生命的基石不是氧核糖核酸（DNA）吗？
