DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is ...

Now, researchers used cryoelectron microscopy (cryo-EM) to elucidate the structure of the Nipah virus polymerase complex ... for both transcription and RNA replication and mutations that have ...

The work provides a detailed three-dimensional picture of the virus's polymerase and its key features. Understanding the structure and behavior of this critical piece of the viral machinery ...

Another important discovery was an intricate RNA structure near the critical "frameshift site" in the viral genome. This frameshift site is essential for the virus to produce the correct ...
