Perhaps, simple replicating RNA molecules, existing before the first cell formed, developed the ability to infect the first cells. Could today's single-stranded RNA viruses be descendants of these ...

RNA is the molecule that reads the genetic information stored in DNA. It's critical for the proper functioning of cells, and in a new study scientists have discovered a way of tagging RNA with a ...

It is a near sphere of protein (cross section shown) inside a fatty membrane that protects a twisting strand of RNA--a molecule that holds the virus's genetic code. Proteins called "S" form spikes ...

A doctor has explained how to avoid a virus which has caused alarm, after a huge outbreak in China. A recent outbreak of the ...

It is a bundle of DNA or RNA bound up in a minuscule core ... “There were features of the virus that made developing a vaccine relatively easy. The next pandemic may not be like that. It’s not going ...

It's relatively simple to deliver RNAi drugs ... When inhaled by mice, though, the short RNA strands reached their targets intact and controlled the virus. Clinical trials for RSV are slated ...

Additionally, the researchers found that flu virus RNA - molecules that carry genetic information but are not considered a health risk - remained detectable in the raw milk for at least 57 days. By ...

The researchers also found that RNA segments in the Z conformation (Z-RNA) in the virus's genome were driving the Nsp13-mediated cell death activation. Since bats express host RHIM proteins ...

Fortunately, advances in enzyme-based, probe-free rRNA depletion technology have brought about a simple tool that is ... on understanding enigmatic RNA viruses that infect the crop without causing ...
