Viruses From Animal and Plants Negative strand ssRNA viruses need to have a preformed replicase when they invade a mammalian cell because they use it to modify host enzymes that are recruited for viral replication None of these use it to terminate transcripts when they copy host cell mRNA have to make a positive strand copy that can be translated use it to modify host enzymes that are recruited for viral replication None of these use it to terminate transcripts when they copy host cell mRNA have to make a positive strand copy that can be translated ANSWER DOWNLOAD EXAMIANS APP
