For the RNA world hypothesis to be accepted, the constitutional self-assembly of RNA will have to be demonstrated. Conceptually, the simplest route to RNA involves nucleotide polymerisation. Activated pyrimidine nucleotides can be derived from arabinose-3-phosphate under potentially prebiotic conditions, but the prebiotic synthesis of this sugar phosphate has not hitherto been investigated. The results
为了接受RNA世界假说,必须证明RNA的结构自组装。从概念上讲,最简单的RNA途径涉及核苷酸聚合。活化的嘧啶核苷酸可以在潜在的益生元条件下衍生自阿拉伯糖-3-磷酸,但是至今尚未研究该糖磷酸的益生元合成。本文描述了涉及磷酸化,磷酸盐迁移和2,3-CC键结构的合成方法的结果。
