Influenza and polio are both caused by single-stranded RNA viruses. The influenza virus particles contain the enzyme RNA polymerase whereas poliovirus does not. What accounts for this difference?
Homework Answers
The copying errors are more in RNA polymerase enzymes than DNA polymerases. Due to this, mutations in RNA viruses occur more frequently as compared to other viruses. This is the reason for them to change and adapt quickly to their host. This is applicable for the diverse range of diseases caused by them and lack of a single effect drug that may be effective against them.
Influenza viruses are called (-) strand RNA viruses because of the polarity of the RNA that is carried in the virion. Another example of RNA viruses is the poliovirus who are (+) strand RNA viruses, the reason being that their genomic RNA can be translated into proteins immediately upon entering the cell.

1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...
