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，我们对它的了解有了长足的发展。

This molecule is DNA, or deoxyribonucleic acid.

该分子是DNA，或脱氧核糖核酸。

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 letters DNA are short for the term deoxyribonucleic acid.

字母 DNA 是术语脱氧核糖核酸的缩写。

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脱氧核糖核酸或 DNA 的东西。

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

细胞生长，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长、发挥功能和繁殖的遗传信息。

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是脱氧核糖核酸的简称，它是动植物细胞内承载遗传信息的物质。
