The ability to evolve is a key characteristic that distinguishes living things from non-living chemical compounds. The construction of an evolvable cell-like system entirely from non-living molecules ...

－実験室での生命誕生過程の再現に向けて－ 理化学研究所（理研）生命機能科学研究センター高機能生体分子開発チームの李佩瑩（リ・ペエイ）研究員、田上俊輔チームリーダーらの国際共同研究チームは、正電荷を持つペプチド[1] 凝集体がRNA[2] を吸着し ...

Researchers from Tokyo University of Science have engineered a ribozyme structure which mimics the early RNA world and provides novel insights on the role of RNA in primitive life, to its various real ...

Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must ...

As a result of this new research, these complex ribozyme sequences in the early stages of RNA evolution are not necessary. "The precision is comparable to the copying of RNA achieved by ribozymes," ...

How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in ...
