These random molecules were fed a collection of three-base-long RNAs, each linked to a chemical tag. The idea was that if a molecule is capable of ligating one of these short RNA fragments to itself, ...

Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...

Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

Premature termination of transcription influences ribosomal RNA output and RNA polymerase I drug sensitivity, revealing a mechanism of resistance to transcription-targeting chemotherapy.

Researchers developed C28, an engineered polymerase that efficiently synthesizes RNA at near-natural speeds with high ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...

DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this ...

Scientists at a secretive Florida DNA lab are analyzing key evidence that could unlock the mystery of Nancy Guthrie's disappearance.

A new medical breakthrough could soon make genetically modified pig organs a viable solution for human transplants!

Mucormycosis is a rapidly progressive, invasive fungal infection that affects patients who are severely immunocompromised, as well as patients with diabetes and persons with immunocompetence who have ...
