SANTA CRUZ, CA — Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction ...

There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...

Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a ...

Nipah virus is a zoonotic virus harbored by fruit bats. It can be transmitted to pigs and humans, infect people through contaminated food, and can travel directly from person to person via droplets.

When RNA molecules are synthesized by cells—a critical process in the creation of proteins and other cellular functions—they typically undergo a series of "folding" events that determine their ...
