Scientists Unravel Critical Genetic Puzzle For Flu Virus Replication

... Much is known about the genes and inner workings of flu viruses. Yet how the microbe organizes its genetic contents to seed future generations of viruses has remained an enduring mystery of biology. Now, with the help of a long-studied flu virus, an electron microscope and a novel idea of how the virus aligns segments of RNA as it prepares to make virions, the particles a virus creates and sends forth to infect cells, that puzzle has been resolved. ...
