DNA stands for deoxyribose nucleic acid.

DNA 代表脱氧核糖核酸。

DNA is a type of nucleic acid.

脱氧核糖核酸（DNA）是一种核酸。

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

肌肉收缩，在全身子，合成脱氧核糖核酸等。

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

等等。但生命的基石不是脱氧核糖核酸（DNA）吗？

There is so much DNA in our cells.

我们的细胞里有如此多的脱氧核糖核酸。

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

脱氧核糖核酸损是导致晒和皮肤癌的原因，最终产生皱纹。

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

但是酶磨损，膜解，脱氧核糖核酸被氧化。所以，它们被丢弃。

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

自从 19 世纪发现脱氧核糖核酸以来，我们对它的解有足的发展。

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 亿英里的脱氧核糖核酸。

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脱氧核糖核酸、肌动蛋白或磷脂双子层所需的东西。

The letters DNA are short for the term deoxyribonucleic acid.

字母 DNA 是术语脱氧核糖核酸的缩写。

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

不管怎样，脱氧核糖核酸测试将给他证明。

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

这些记录包含有关 DNA 的信息，DNA 是脱氧核糖核酸的缩写。

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

细胞生，遗传和遏制由其DNA（脱氧核糖核酸）控制。

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理限制：脱氧核糖核酸。

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

DNA，即脱氧核糖核酸，是决定我们身体如何生、发挥功能和繁殖的遗传信息。

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

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

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，由你的脱氧核糖核酸定义。

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，核酸酶将脱氧核糖核酸和核糖核酸解成核苷酸。

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，可以吸收紫外线，防止其损害皮肤中的脱氧核糖核酸。
