Abstract
The proposal that RNA preceded DNA in evolution is more than 15 years old. In light of recent studies on RNA processing (including protein-free reactions), present knowledge about eukaryotic gene structure, and studies comparing ribosomal RNA sequences, we propose a train of events for precellular and early cellular evolution.
摘要
RNA在进化中先于DNA出现的这一观点已有超过15年的历史。鉴于最近关于RNA加工（包括无蛋白质反应）的研究、目前对真核基因结构的了解以及比较核糖体RNA序列的研究，我们提出了一系列关于细胞前和早期细胞进化的事件。
