Blueprint of Planetary Intelligence] Vol. 35 The Dawn of the RNA World: The Dual Drive of Catalysis and ...
Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth—a key process in the origin of life. Scientists ...
Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...
We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
UC San Diego structures show E. coli RNA polymerase reads four synthetic DNA letters the same way it reads the natural four.
Scientists have identified a previously unrecognized layer of the human genome. It's built not from DNA's usual building blocks, but from small fragments of RNA embedded directly inside it. Georgia ...
A soybean enzyme better known for its role in plant hormone chemistry has been unmasked as an unexpected accomplice of a ...
Every time a cell divides, it must copy roughly three billion letters of DNA with near-perfect fidelity. That copying process, DNA replication, is among the most demanding operations a cell performs, ...
