生命科学Life scienceRNA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 hypothesis）”推测，RNA在远古生命中可能承担更广泛的功能 ...

The RNA world hypothesis gains support from the in vitro evolution of a bifunctional ribozyme that can recognize an activated glutaminyl ester and subsequently aminoacylate a tRNA molecule.

The involvement of noncoding mRNAs in many regulatory processes, their abundance, and their diversity of functions has led to the hypothesis that an "RNA world" may have preceded the evolution of ...

was the chemical that led directly to life is termed the RNA world hypothesis. Although the phrase "RNA world" is generally attributed to Walter Gilbert, Harvard University's Carl M. Loeb University ...

“It’s definitely a key advance in the field of understanding what RNA polymerase ribozymes can do, and it has pretty important implications for the RNA world theory,” he added. Study coauthors Gerald ...
