Even though viruses are known to take over the host cell's metabolism and use the host enzymes for the viruses' own processes, certain enzymes must be supplied by the RNA viruses because these enzymes translate viral mRNA into proteins. host cells lack enzymes that can replicate the viral genome. host cells rapidly destroy the viruses.
