RNA has a base, uracil, or U, whereas DNA has the base thymine or T.

RNA 的碱基是尿（U），而 DNA 的碱基是（T）。

Adenine will always bind with thymine and cytosine with guanine.

嘌呤总是与结合，与鸟嘌呤结合。

The Nitrogenous bases are of four different types: Adenine, Guanine, Cytosine and Thymine.

含氮碱基有四种不同的类型：嘌呤、鸟嘌呤、和。

There are four bases: adenosine, thymine, cytosin, and guanine.

苷、、和鸟嘌呤。

Silver sulfadiazine is still used to dress burns.

磺胺银仍用于包扎烧伤。

Guanine always pairs with cytosine and adenine always pairs with thymine.

鸟嘌呤总是与配对，嘌呤总是与配对。

Set me up for a high volume irrigation and grab me some silvadene.

准备大量冲洗和磺胺银。

Purine position 1 to pyrimidine position 1, purine position 6 to pyrimidine position 6.

嘌呤位置 1 到位置 1，嘌呤位置 6 到位置 6。

To understand where the uric acid comes from, let's start with purines, which, together with pyrimidines, are nature's most common nitrogen-containing heterocycles.

为了说明尿酸从何而来，让我们先来了解嘌呤和，它们都是自然界中最常见的含氮杂环。

These are the letters of RNA or the letters of DNA. Cytosine, guanine, adenine and uracil in RNA.

这些是核糖核酸（RNA）或脱氧核糖核酸（DNA）的字母。在RNA中，它们分别是、鸟嘌呤、嘌呤和尿。

And so in RNA, it's adenine, guanine, uracil and cytosine.

在核糖核酸中，它们是嘌呤、鸟嘌呤、尿和。

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，叶酸对制造红细很重要，和是构成脱氧核糖核酸的四种碱基中的两种。

See, DNA is made up of four different building blocks called " bases" : adenine, cytosine, guanine, and thymine.

看，DNA 由四种称为“碱基”的不同构件组成：嘌呤、、鸟嘌呤和。

So you've got cytosine, guanine, adenine and uracil.

所以你有、鸟嘌呤、嘌呤和尿。

If you look at DNA the bases that we have are cytosine, guanine, adenine and thymine.

如果你看脱氧核糖核酸，我们有的碱基是、鸟嘌呤、嘌呤和。

In RNA it's going to be a uracil.

在核糖核酸中，它将会是尿。

In DNA it's going to be thymine.

在DNA中，它（与嘌呤配对的碱基）将是。

It was known that DNA had four chemical components - called adenine, guanine, cytosine, and thiamine - and that these paired up in particular ways.

当时已经知道，DNA含有4种化学成分——嘌呤、鸟嘌呤、和——这4种成分总是以特殊的配对方式排列。

The bases - the letters of the genetic alphabet - consist of the four nucleotides mentioned a page or two back: adenine, thiamine, guanine, and cytosine.

碱基——基因子母表中的字母——由前面我们提到的嘌呤、鸟嘌呤、吟和4种核苷酸组成。

Cytosine, guanine, adenine and thymine in DNA. The other difference here is in DNA. We actually have a double helix so those attach together.

在脱氧核糖核酸（DNA）中，含有、鸟嘌呤、嘌呤和。这里的一个不同之处在于DNA，我们实际上拥有的是双螺旋结构，因此这些碱基对会相互配对连接。
