RNA不仅是遗传信息的载体，还能作为催化分子促进化学反应。尽管目前已知的天然核酶主要催化核酸的断裂与连接反应，但“RNA世界假说（RNA world ...

在众多假说中，RNA世界假说(RNA world hypothesis)因其能够解释遗传信息存储与催化功能统一而备受关注。然而，这一假说面临一个关键挑战：如何实现RNA的自我复制？虽然已有研究表明RNA聚合酶核酶(ribozyme) ...

The RNA World Hypothesis is a concept put forth in the 1960s by Carl Woese, Francis Crick and Leslie Orgel. It proposes that earlier life forms may have used RNA alone for the storage of genetic ...

The RNA World hypothesis resolves the chicken-and-egg conundrum posed by the structure of growth shared by all living organisms. DNA encodes RNA, which directs the synthesis of proteins.

The RNA world is a widely accepted hypothesis that explains two aspects of the origin of life: the start of metabolism and the origin of genetic information. In the RNA world, both the ...

It Sure Looks Like the RNA World Hypothesis Is Wrong. A new discovery suggests life on Earth began much differently than we thought. By Caroline Delbert Published: Dec 29, 2020 9:55 AM EST.

BUFFALO, N.Y. — The RNA world theory suggests that life on Earth began with RNA molecules that copied themselves. It’s believed this self-replication eventually gave rise over millions of years to DNA ...
