The ribose of one nucleotide joins with the phosphate of the next to form the RNA backbone.
一个核的核糖和下一个磷酸盐相连，形成核糖核酸的支柱。
They were probably simpler than any cell now alive, and may have lacked not only protein-based catalysis, but perhaps even the familiar genetic macromolecules, with their ribose-phosphate backbones.
他们可能比现在任何一种活着的细胞都简单，也许既缺乏蛋白质催化酶，也没有我们熟悉的具磷酸核糖股价的遗传大分子。
ADP (adensine diphosphate) A nucleotide consisting of adenine and ribose with two phosphate groups attached. The second phosphate is attached to the first by a high-energy bond.
