Discover how a tiny RNA molecule serves as a molecular switch in viral infections, providing insights into phage biology.

Sean Ryder, professor at UMass Chan Medical School, has written a book to delve the mysteries of ribonucleic acid as a tool to fight diseases. Messenger ribonucleic acid, or mRNA, is in the public ...

Scientists successfully extract RNA from a 130-year-old Tasmanian tiger, thylacine, revealing how its genes functioned before its extinction.

Ribonucleic acid, also called RNA, is a molecule present in all living cells. It plays a critical role in transmitting genetic instructions from DNA and creating proteins. With the power to execute a ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

Chemists at University College London have shown how two of biology's most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

An innovative three-color method for capturing images of mRNA inside live mammalian cells has been developed by UMass Amherst chemists. Because RNA is both incredibly important to human life and ...
