   Recent biochemical studies have revealed that the single-stranded RNA of several coronaviruses is polyadenylated, indicating that it is probably of positive polarity, and the genome of infectious bronchitis virus has been reported to be infectious, supporting evidence that the coronavirion RNA has a message function.
