RNA world - Wikipedia
The RNA world is a hypothetical stage in the evolutionary history of life on Earth in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. [1] The term also refers to the hypothesis that posits the existence of this stage.

One view is that an RNA world existed on Earth before modern cells arose (Figure 6-91). According to this hypothesis, RNA stored both genetic information and catalyzed the chemical reactions in primitive cells.

1986年，随着多种RNA核酶催化活性的发现，Walter Gilbert首次提出了“the RNA world”的假说 [1]。 他设想了一个原始的、只含有RNA的世界：RNA分子催化自我复制，通过自我剪接产生具有功能活性的RNA分子，通过内含…

RNA世界假说，英文为RNA World hypothesis，是科学家依据多年的科学研究而提出的一条关于生命科学的理论。 其内容为：生命进化的早期，没有蛋白质（酶），某些RNA可以催化RNA的复制——也就是说RNA是唯一的遗传物质，是生命的源头。

Jul 6, 2022 · The RNA world hypothesis — which postulates that RNA with both genetic information and catalytic activity had an essential role in the origin of life — is now supported by many scientists.
The Origins of the RNA World - PMC - PubMed Central (PMC)
The general notion of an “RNA World” is that, in the early development of life on the Earth, genetic continuity was assured by the replication of RNA and genetically encoded proteins were not involved as catalysts. There is now strong evidence indicating that an RNA World did indeed exist before DNA- and protein-based life.
The RNA world - NobelPrize.org
The RNA World referred to an hypothetical stage in the origin of life on Earth. During this stage, proteins were not yet engaged in biochemical reactions and RNA carried out both the information storage task of genetic information and the full range of catalytic roles necessary in a very primitive self-replicating system.

RNA世界学说 （英语： RNA world hypothesis ）是一个关于 生命 起源的理论，认为地球上早期的生命 分子 以RNA先出现，之后才是DNA。且这些早期的RNA分子同时拥有如同DNA的遗传讯息储存功能，以及如蛋白质般的催化能力，支持了早期的细胞或前细胞生命的运作。
