8
New cards

What does segmented mean?

genome splits into separate pieces

  • easy to shuffle and mix

9
New cards

Which 2 viruses have segmented genomes?

Influenza (Orthomyxovirus) & Rotavirus (Reovirus)

10
New cards

What does non-segmented mean/

one long piece genome

  • glued together, cant swap pieces

11
New cards

Why can Influenza A undergo antigenic shift?

Because it has a segmented genome
