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 ...

Influenza A virus (IAV) possesses a segmented, negative-sense RNA genome comprising eight distinct viral RNA (vRNA) segments. These segments form ribonucleoprotein (RNP) complexes that are selectively ...

This seminar explores the link between modern RNA and suggestions for a prebiotic RNA world that existed some 3.8 billion years ago. Topics include prebiotic synthesis, replication and in vitro ...

Bacteriophages, or phages for short, are viruses that infect bacteria. Using phages therapeutically could be very useful in fighting antibiotic-resistant pathogens, but the molecular interactions ...

For decades scientists have recognized that human immunodeficiency virus (HIV) is a formidable viral pathogen. After years of probing work and extensive experimentation, a Yale research team has ...

There is currently no cure for HIV, but medications can help people with the disease manage their symptoms. HIV can still develop into AIDS years after infection, however, even with disease management ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.

On the left are three forms of the same RNA molecule, which is stabilised into a single form (on the right) by mitoxantrone. Ribonucleic acids (RNAs) serve as messengers between DNA and protein ...

All five canonical nucleobases, which form the basis of DNA and RNA that carry genetic information, were found in sand samples taken from the asteroid Ryugu by the Japanese Hayabusa 2 probe, ...

A team at UT Southwestern Medical Center has identified a structural trick that lets viruses translate their genetic code inside human cells, even when that code is riddled with “bad” codons the host ...
