1·Adenylate kinase (AK) is a phosphotransferase enzyme that catalyzes the interconversion of adenine nucleotides, and plays an important role in cellular energy homeostasis.

腺苷酸激酶(AK)是催化各种腺嘌呤核苷酸相互转化的一种磷酸转移酶，其在维持细胞能量平衡中起着重要的作用。

2·This article's examples use DNA, which consists of two strands of adenine (A), cytosine (C), thymine (T), and guanine (G) nucleotides.

本文的示例使用 DNA，DNA 由腺嘌呤（A）、胞嘧啶（C）、胸腺嘧啶（T）和鸟嘌呤（G）组成的核苷酸双螺旋组成。

3·Of the four nucleotides that comprise DNA molecules, adenine, turns out to have a particularly high affinity for gold.

在组成 DNA分子的四种核苷分子中，属腺嘌呤与金的亲合力最强。
