Question

Quizplus · Accepted Answer

dsRNAs are not normally produced by the cell's genetic activities, indicating that their presence is likely due to an invasion by foreign genetic material, such as viral RNA. RNAi provides a defense mechanism for the cell to degrade these foreign RNAs and prevent their replication/infection.
