Why Do Many Positive-Strand RNA Viruses Form Their Genome Replication

question 20

Multiple Choice

Why do many positive-strand RNA viruses form their genome replication complexes on the surface of cytoplasmic membranes?

• A) Genome replication requires cellular membrane bound proteins.
• B) This allows the RNA to be replicated close to the site of virion assembly.
• C) The membrane acts as a nucleation sites to bring all of the proteins together.
• D) The membrane protects the viral genome during replication.
• E) Fatty acids are required co-factors of the viral polymerase.
