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 ...

COLUMBUS, Ohio – 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 ...

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 ...

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

RNA is thought to have sparked the origin of life by self-copying. Researchers have now revealed the atomic structure of an 'RNA copy machine' through cryo-EM. This breakthrough sheds light on a ...

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, ...

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 ...
