Compared to DNA viral replication, RNA viral replication is more susceptible to mutation because

Compared to DNA viral replication, RNA viral replication is more susceptible to mutation because Correct Answer RNA replication lacks the proofreading functions characteristic of DNA replication.

D. The RNA of RNA viruses is copied by an RNA polymerase or reverse transcriptase. Neither enzyme has a proofreading function or the ability to repair copying errors. As a result, RNA viruses mutate much faster than DNA viruses.
