Scientists have created an artificial RNA system that can copy itself using simple building blocks and temperature changes.

What if we've made a mistake about the origin of life? For decades, primordial soup was the reigning hypothesis, but a new flood of discoveries is upending this tale and revealing a far more ...

End of RNA world hypothesis? The researchers, whose study has now been published in Nature Communications, demonstrated that the formation of the RNA molecules increased by up to 100-fold in the ...

The book begins with the hypothesis that RNA, because it has both informational and catalytic capacity, was the ancestor of both DNA and proteins, albeit with sobering reminders in subsequent ...

本研究针对RNA世界假说中RNA自我复制的关键问题，通过冷冻电镜技术系统研究了小环状RNA (scRNA)模板在滚环合成 (RCS)过程中形成的二聚体中间体结构。研究人员发现这些中间体可形成多种RNA纳米结构，其中完全杂交的二聚体复合物最为稳定。该研究不仅揭示了二聚体作为复制'存储'形式的潜在作用 ...
