Plant defenses against RNA viruses involved which of the following?

Question

Quizplus · Accepted Answer

Plant defenses against RNA viruses involve all of the given components: siRNAs, RISC, Dicer, and host RNA-dependent RNA polymerase. These components work together to recognize and degrade viral RNA, preventing the virus from replicating. siRNAs are small RNA molecules that bind to target viral RNA and guide RISC to degrade it. Dicer is an enzyme that cleaves longer RNA molecules into shorter, functional siRNAs. The host RNA-dependent RNA polymerase uses these siRNAs as templates to produce more siRNAs, amplifying the antiviral response. Therefore, all of the above choices are correct.
