Adenine will always bind with thymine and cytosine with guanine.

腺嘌呤总是与胸腺结合，与鸟嘌呤结合。

For this, they looked at an organ called the thymus.

为此，他们检查了研究对象的胸腺。

Now, T-cell development starts in the thymus from precursors that arise in the bone marrow.

Usually, our thymus makes sure that the T-cells that attack these self proteins aren't allowed to survive.

一般情况下，我们的胸腺灭活这些攻击自身蛋白的T细。

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

腺苷、胸腺、和鸟嘌呤。

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：腺嘌呤、鸟嘌呤、和胸腺。

But Duke University waited to announce the operation until after doctors learned whether the thymus implants were working.

About two weeks later, he had a second operation to implant the processed thymus tissue.

大约两周后，他进行了第二次手术，将经过处理的胸腺组织植入。

However, in this study, the T-cell production by the thymuses of the cyclists had not slowed down with age.

不过, 在这项研究中, “骑行队”胸腺的T细生成并没有因年龄增长而放缓。

His own partly working thymus was removed so that new immune cells can develop.

他自己部分工作的胸腺被切除，这样就可以产生新的免疫细。

The tissue came from another person's thymus gland and was partly grown in a laboratory.

该组织来自另一个人的胸腺，在某种程度上是在实验室中培养出来的。

The thymus makes immune cells called T-cells.

胸腺产生称为 T 细的免疫细。

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

鸟嘌呤总是与配对，腺嘌呤总是与胸腺配对。

The thymus enables T cells to mature.

胸腺使T细成熟。

I would look at GHK, thymus and beta, BPC-157.
