The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead ...

RNA probably came before DNA, serving as the storehouse of genetic information and driving chemical reactions; a ...

Now, a pair of Scripps Research Institute scientists has taken a significant step toward answering that question. The scientists have synthesized for the first time RNA enzymes that can replicate ...

A newly identified class of RNA molecules has been discovered in bacteria living inside the human body. These circular genetic structures, termed obelisks, differ from known viruses and bacteria and ...

A breakthrough experiment, published in the Proceedings of the National Academy of Sciences, offers compelling support for ...

(Nanowerk Spotlight) Nucleic acids are becoming increasingly popular for assembling nanoscale structures, thanks to their programmable dimensionality and direct applications in the biological field.

What makes ribozymes particularly interesting is that they are amenable to tinkering. Creation of a protein enzyme de novo, or modification of an existing one to function in a different way, is a ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper of ...

Image showing activity-induced local expression of long noncoding RNA Gas5 in primary cortical neurons, in vitro. Red and blue indicate Gas5 and DAPI, respectively. Synaptic marker, PSD95 is labelled ...

Researchers have discovered a new way ribonucleic acid (RNA) impacts fear-related learning and memory. Researchers demonstrated that a noncoding RNA known as Gas5 coordinates the trafficking and ...
