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

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

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

The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like ...

SANTA CRUZ, CA — Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction ...

RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...

Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells. RNA molecules are real all-rounders. They transfer the genetic information from ...

The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a deoxyribose ...

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 ...
