Scientists have identified an RNA that they named 'lncREST' (long non-coding RNA REplication STress) and uncovered its role in triggering an effective response to the stress induced by rapid cell ...

In a recent study posted to bioRxiv*, researchers evaluated the early replication kinetics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Study: Visualization of early 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 ...

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 ...

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 ...

Viruses are entities that have to infect other cells in order to replicate. They may have genomes that are made of DNA or RNA. We are still discovering new types of RNA viruses, as shown in two new ...

On the left is integrase in its “intasome” structure of four identical four-part complexes (pink) that connect to create one 16-part complex that locks around viral DNA (blue). On the right is ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have ...

Researchers at Cold Spring Harbor Laboratory found that Dicer, an ancient RNA-cutting protein shared by humans and yeast, ...
