1. Negative strand RNA synthesis

2. - Sense RNA genomes
Unimolar
Segmented

3. What does segmented mean?
Genome in segments often representing different genes.
Segmented genomes confer evolutionary advantages.
Different strains of a virus with a segmented genome can shuffle and combine genes and produce progeny viruses or (offspring) that have unique characteristics.
This is called reassortment 

5. Vesicular Stomatitis Virus (VSV)

6. The VSV Genome

7. Uses of – sense template

8. Capping and polyadenylation mechanism of viral RNA different to host mRNA and is carried out by host encoded enzymes.

9. Switch from translation to replication

12. Influenza Virus Segmented – sense RNA

13. The genome

14. Marking strands for packaging

15. N Protein

16. Nucleocapsids are transported into the nucleus.
mRNA synthesis and replication of viral RNA occurs in the nucleus. 
This is very unusual for an RNA virus. Influenza virus has an unusual mechanism for acquiring a methylated, capped  5'end to its mRNAs.
A viral endonuclease (which is packaged in the influenza virus) snips off the 5'end of a host capped, methylated mRNA about bases from the 5' end and uses this as a primer for viral mRNA synthesis.
Hence all flu mRNAs have a short stretch at the 5' end which is derived from host mRNA.

17. Capping from host mRNA (cap snatching)

19. RNA synthesis from dsRNA genomes

20. dsRNA viruses Contain dsRNA segmented genomes Viral polymerase

23. The genome

26. Negative Strand Viruses
Contain enzymes for transcription in virion
Make mRNA prior to antigenome
Message gets capped; genome does not
Plus strand is template for minus strand genome
Makes more minus than plus strand
