The present invention provides artificial universal base capable of base pairing nonspecifically with any of four kinds of natural nucleic acid bases (A, T, G, and C) without the function to specifically recognize pairing natural nucleic acid bases for base pair formation.
Universal base capable of base paring nonspecifically with four kinds of natural nucleic acid bases, wherein the universal base has a structure represented by the following chemical formula:
wherein R represents a monovalent group other than a hydrogen atom.
本发明提供了一种人工通用碱基,能够与任何四种天然核酸碱基(A、T、G和C)非特异性配对,而无需具有特异性识别天然核酸碱基的功能,以形成碱基对。通用碱基能够与四种天然核酸碱基非特异性地配对,其中通用碱基具有以下
化学式所表示的结构:其中R代表一个单价基团,而不是氢原子。
