- top: positive sense
- middle: negative sense. Nucleic acid not translatable. Must be translated by RNA polymerase, flip 3' and 5' and flip base, strand now looks like +RNA
Replication
- -RNA used to make +RNA genome
- +RNA used to make -RNA genome
DNA
Infectivity
- infectivity: whether or not genetic material can be infectious by itself
Segmented
