A ribozyme found by accident selectively repairs broken RNA, suggesting early life could have preserved its genetic code ...

Researchers seeking to understand how life may have emerged from Earth’s primordial soup have found an interesting behavior of ribonucleic acid (RNA), which they suggest could have given way to ...

In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At ...

In most modern cells, DNA stores the genetic blueprint, and relies on proteins to replicate, repair and build from those ...

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 ...

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 ...

Researchers from Stockholm University have—for the first time ever—managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths. These RNA sequences are the oldest ever ...

A much-debated theory holds that 4 billion years ago, give or take, long before the appearance of dinosaurs or even bacteria, the primordial soup contained only the possibility of life. Then a ...

MINING FOR RNA: James Ferris's group at Rensselaer re-creates how nucleotides might have joined on ancient mineral surfaces. The RNA world hypothesis has fueled diverse research approaches, drawing ...
