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

Researchers at the University of Tokyo have created an RNA molecule that can not just replicate, but “evolve” into a diverse range of more complex molecules. This find could plug a major gap in the ...

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 ...

HIV replication in the human body requires that specific viral RNAs be packaged into progeny virus particles. A new study has found how a small difference in the RNA sequence can allow the viral RNA ...

Cells use the genetic information contained in DNA to generate proteins, which carry out many of the processes of life. RNA is the intermediate molecule; it is transcribed from DNA, then edited, ...

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 ...
