DNA is a type of nucleic acid.

氧核糖核酸（DNA）是一种核酸。

That DNA damage is what causes sunburn, skin cancer, and eventually wrinkles.

氧核糖核酸损伤是导致晒伤和皮肤癌的原因，最终产生皱纹。

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

肌肉收缩，在全身运输分子，合成氧核糖核酸等。

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？

DNA stands for deoxyribose nucleic acid.

DNA 代表氧核糖核酸。

There is so much DNA in our cells.

我们的胞里有如此多的氧核糖核酸。

But enzymes wear out, and membranes break down, and DNA gets oxidized. So, they get discarded.

但是酶磨损了，膜分解了，氧核糖核酸被氧化了。所以，它们被丢弃了。

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。

So if you multiply that out, you get 40 billion miles of DNA.

所以如果你把它相乘，你会得到 400 亿英里的氧核糖核酸。

But you can't just breathe in the stuff you need to build DNA, or actin, or a phospholipid bilayer.

但是你无法仅仅靠呼吸来构建氧核糖核酸、肌动蛋白或磷脂双分子层所需的东西。

The records had information about DNA, short for deoxyribonucleic acid.

这些记录包含有关 DNA 的信息，DNA 是氧核糖核酸的缩写。

The letters DNA are short for the term deoxyribonucleic acid.

字母 DNA 是术语氧核糖核酸的缩写。

One way or the other, the DNA test will give him proof.

不管怎样，氧核糖核酸测试将给他证明。

The cell growth, inheritance and containment is controlled by its DNA (deoxyribonucleic acid).

胞生长，遗传和遏制由其DNA（氧核糖核酸）控制。

DNA. I mean, it uses protein, it uses our  chemistry, but it's it's doing something weird.

氧核糖核酸。我的意思是，它使用蛋白质，它使用我们的化物质，但它正在做一些奇怪的事情。

DNA, or deoxyribonucleic acid, is the genetic information that dictates how our bodies grow, function, and reproduce.

DNA，即氧核糖核酸，是决定我们身体如何生长、发挥功能和繁殖的遗传信息。

But we might have something inside us that can outlast these physical limitations: deoxyribonucleic acid.

但是我们内心可能有一些东西可以超越这些物限制：氧核糖核酸。

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合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。

Amylase, meanwhile, reduces carbs to glucose and fructose, and nuclease busts the nucleic acids that are in DNA and RNA into nucleotides.

与此同时，淀粉酶将碳水化合物还原为葡萄糖和果糖，核酸酶将氧核糖核酸和核糖核酸分解成核苷酸。

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年前，Miescher 第一个确定了后来被称为氧核糖核酸或 DNA 的东西。
