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 ...

Liquid brine veins, where RNA molecules can replicate, surround solid ice crystals in water ice, as seen with an electron microscope. Chemists at UCL and the MRC Laboratory of Molecular Biology have ...

They say that change takes time. Well, that's not the case for RNA. The small biological molecule acts like a switchboard operator, capable of changing its shape every few milliseconds so it can ...

UMBC scientists uncovered how enteroviruses initiate replication by assembling a conserved RNA–protein complex inside host cells. The team showed how viral and host proteins bind an RNA cloverleaf to ...

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 ...

Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. Like other viruses, the dengue virus is a microscopic structure that can only replicate ...

RNA is usually portrayed as a molecule that works deep inside the cell, helping to turn genetic information into proteins.

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 ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has ...
