Faithful duplication of the genome demands precise coordination between DNA replication and RNA transcription, two processes that share and compete for the same DNA template. When replication forks ...

The Okazaki Fragments That Solved the Mystery of DNA Replication1. The Mystery That Could Not Be Solved by the Discovery of ...

Blueprint of Planetary Intelligence] Vol. 35 The Dawn of the RNA World: The Dual Drive of Catalysis and ...

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 ...

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, ...

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 ...

Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is ...

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 ...

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages ...

UC San Diego structures show E. coli RNA polymerase reads four synthetic DNA letters the same way it reads the natural four.
