Chapter 17.2, Problem 2CC
MAKE CONNECTIONS The RNA virus in Figure 17.7 has a viral RNA polymerase that functions in step 3 of the virus’s replicative cycle. Compare this with a cellular RNA polymerase In terms of template and overall function (see Figure 14.10).

Draw a generic (+)RNA virus replication cycle. For viruses, (+) RNA indicates the genomic RNA can be translated directly. How would this differ from the system you drew in #1?
Draw a generic (+) RNA virus replication cycle. Indicate which proteins need to be present for RNA replication and translation. Where would they act?
Indicate what sequences or modifications would need to be present on the virus RNA for RNA replication and translation.
How might a virus differentiate between RNA to be put into progeny virus particles and RNA to be translated into protein?

Many virologists note that viruses which have a genome made up of RNA will tend to evolve faster than those viruses whose genome is made up of double-stranded DNA.
Most evolutionary biologists now accept that RNA was the first nucleic acid molecule to evolve to store information. Why is this early “RNA world” more likely when you consider how RNA polymerases (such as primase) and DNA polymerases start replicating nucleotide chains?
