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

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

Findings uncover the architecture of a key viral complex, showing how RNA interaction and protein assembly drive replication ...

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 ...

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 ...

Cryo-EM reveals the first detailed structure of the Bornavirus nucleoprotein–RNA complex, uncovering unique RNA binding and assembly mechanisms.

For 400 million years, a leading hypothesis claims, Earth was an “RNA World,” meaning that life must’ve first replicated from RNA before the arrival of proteins and DNA. Unfortunately, scientists have ...

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 ...
