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嘧啶，它们都自然界中最常见含氮杂环。

Nucleotides of DNA are made up of a sugar - deoxyribose, a phosphate, and one of the four nucleobases - adenine, cytosine, guanine, and thymine - or A, C, G, T for short.

DNA核苷酸由一分子单糖-脱氧核糖、一分子磷酸与四核之一腺嘌呤（A）、胞嘧啶（C）、鸟嘌呤（G）或胸腺嘧啶（T）组成。

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

——因子母表中字母——由前面我们提到腺嘌呤、鸟嘌呤、胞嘧吟和胸腺嘧啶4核苷酸组成。

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

腺苷、胸腺嘧啶、胞嘧啶和鸟嘌呤。

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

含氮有四不同类型：腺嘌呤、鸟嘌呤、胞嘧啶和胸腺嘧啶。

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

鸟嘌呤总与胞嘧啶，腺嘌呤总与胸腺嘧啶。

And in the States, Oregon has opened up the possibility of cytosine therapy for wellness, not for illness, but for wellness across the whole state and as has Colorado now.

在美国，俄勒冈州已开始探索胞嘧啶疗法用于健康保健，而非治疗疾病，而面向全州范围健康促进；科罗拉多州如今也已如此。

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

看，DNA 由四称为“”不同构件组成：腺嘌呤、胞嘧啶、鸟嘌呤和胸腺嘧啶。

准备大量冲洗和磺胺嘧啶银。

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

嘌呤位置 1 到嘧啶位置 1，嘌呤位置 6 到嘧啶位置 6。

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，我们有胞嘧啶、鸟嘌呤、腺嘌呤和胸腺嘧啶。

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

这些核糖核酸（RNA）或脱氧核糖核酸（DNA）字母。在RNA中，它们分别胞嘧啶、鸟嘌呤、腺嘌呤和尿嘧啶。

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

所以你有胞嘧啶、鸟嘌呤、腺嘌呤和尿嘧啶。

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，含有胞嘧啶、鸟嘌呤、腺嘌呤和胸腺嘧啶。这里一个不同之处在于DNA，我们实际上拥有双螺旋结构，因此这些会相互连接。
