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）是核酸。

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

肌肉收缩，在全身运输分子，合成脱氧核糖核酸等。

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

等等。但命基石不是脱氧核糖核酸（DNA）吗？

There is so much DNA in our cells.

我们细胞里有如此多脱氧核糖核酸。

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

脱氧核糖核酸损伤是导致晒伤和皮肤癌原因，最终产皱纹。

" In response to that, Congress in 2005 enacts the Combat Methamphetamine Act."

“作为回应，国会在 2005 年颁布了《打击脱氧麻黄碱法案》。”

Now, deoxygenated blood then feeds back into larger and larger veins, and goes back to the heart.

之后，脱氧血液逐级回流到静脉血管中，并最终返回心脏。

RNA has a sugar called ribose, whereas DNA has a sugar called deoxyribose.

RNA 有叫做核酸糖糖，而 DNA 有叫做脱氧核糖糖。

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，脱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 世纪发现脱氧核糖核酸以来，我们对它了解有了长足发展。

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 亿英里脱氧核糖核酸。

Then, using a technology called the Sanger method, each piece was sequenced letter by letter.

随后，他们运用“桑格测序法” （注：双脱氧链终止法）将每个片段内碱基进行逐测序 （即A, T, C, G）。

Especially since rusty metal can create jagged wounds with lots of deoxygenated dead tissue for them to latch onto.

尤其是锈金属会造成锯齿状伤口，带来大量脱氧坏死细胞组织，伤口更易被附着（破伤风梭菌）。

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、肌动蛋白或磷脂双分子层所需东西。

The letters DNA are short for the term deoxyribonucleic acid.

字母 DNA 是术语脱氧核糖核酸缩写。

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。

And so what deoxyglucose is a molecule that's a whole lot like glucose.

那么脱氧葡萄糖是与葡萄糖非常相似分子。

The pulmonary arteries carry deoxygenated blood from the heart to the lungs.

肺动脉将脱氧血从心脏输送到肺。

And what he did was he used a method called deoxyglucose.

而他所做是他使用了叫做脱氧葡萄糖方法。
