RNA Interference is Triggered by ـــــــــــــــ

Question

RNA interference is triggered by ـــــــــــــــ.
A)dsDNA
B)dsRNA
C)ssDNA
D)ssRNA

Accepted Answer

RNA interference is triggered by double-stranded RNA (dsRNA), which is processed by the enzyme Dicer into small interfering RNAs (siRNAs) that can then bind to and degrade homologous mRNA molecules, leading to post-transcriptional gene silencing. dsDNA and ssDNA do not trigger RNA interference, and ssRNA is not a common trigger for this process, although some RNA viruses can produce dsRNA intermediates during their replication cycle, which can then elicit RNA interference in infected cells.
