Answer:
The influenza virus has a negative sense RNA genome. In order to replicate, this means that the virus must first produce positive sense mRNA in order to produce necessary enzymes. Once the enzymes are translated, replication can take place. Positive sense cRNA is then made from the original negative sense RNA, using the enzymes. Negative sense RNA progeny are then made from the positive sense cRNA. The final viral progeny eventually bud from the host cell, ready to infect other cells.
