Silver turns up the A-C: In the presence of Ag(I) ions, a DNA polymerase incorporated deoxyadenosine (from dATP) at the site opposite cytosine in the template strand to afford the full-length product (see scheme), meaning that DNA polymerases prefer a C-Ag(I)-A base pair to the more thermodynamically stable C-Ag(I)-C base pair.
银使 A-C 配对:在 Ag(I)离子存在的情况下,DNA 聚合酶在模板链上与胞嘧啶相对的位置掺入脱氧腺苷(来自 dATP),从而得到全长产物(见方案),这意味着 DNA 聚合酶更喜欢 C-Ag(I)-A 碱基对而不是热力学更稳定的 C-Ag(I)-C 碱基对。
