What would the result be if a drug that blocks the action of rna polymerase was introduced into a virus-infected organism?
Svetllana [295]

Answer:

The correct answer is: viral replication would stop.

Explanation:

Drugs that block the action of RNA polymerase in viruses are called antivirals and are used to cure viral infections like Hepatitis and Herpes.

<u>Antivirals do not destroy the virus but rather mess with its development by inhibiting its replication</u>.

Viruses do not have the capacity to replicate or synthesize proteins by themselves, so they need a host that can "lend them" the structures needed to perform those processes. If the drug blocks the RNA polymerase, the virus won't be able to replicate itself.
