Scientists discover QT45, a self-replicating RNA molecule, offering insights into the origins of life on Earth.

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA ...

The brain’s ability to do everything from forming memories to coordinating movement relies on its cells producing the right proteins at the right time. But directly measuring this protein production, ...

UCLA researchers have developed a lipid nanoparticle-based gene-editing approach capable of inserting an entire healthy gene into human airway cells, restoring key biological function in a laboratory ...

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 ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

Abstract: Due to their sequential nature, traditional DNA synthesis methods are expensive in terms of time and resources. They also fabricate multiple copies of the same strand, introducing redundancy ...

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

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 ...

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, ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...
