The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) are responsible for kickstarting evolution ...

Chemists have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth -- a key process in the origin of life. Chemists at UCL and the MRC Laboratory of Molecular Biology ...

A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early ...

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth—a key process in the origin of life. Scientists ...

This story is part of our series on viroids and virusoids, small infectious RNAs. The story is also the second installment in a series on hepatitis D virus, a virusoid-like pathogen that causes ...

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 ...

MADISON — RNA viruses, such as the coronavirus that causes COVID-19, are in a life-and-death race the moment they infect a cell. These viruses have only minutes to establish their replication ...

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...

Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and ...
