Chemical tags affect ability of RNA viruses to infect cells

Large swaths of DNA and its lesser-known cousin RNA are dotted by chemical tags that act like Post-It notes, providing additional instructions to the underlying genetic code. The most abundant of these RNA modifications goes by the name N6-methyladenosine, and has been implicated in a variety of biological processes. But very little is known about its role in infectious diseases. New research shows that RNA viruses are littered with N6-methyladenosine tags which affect the ability of these virus...
