Question

select the correct answer.
which form of genetic material initiates rna interference?
a. double - stranded dna
b. double - stranded rna
c. single - stranded dna
d. single - stranded rna

Explanation:

RNA interference (RNAi) is initiated by double - stranded RNA (dsRNA). When dsRNA is present in a cell, it is processed into small interfering RNA (siRNA) or microRNA (miRNA), which then mediate the silencing of target genes. Double - stranded DNA, single - stranded DNA, and single - stranded RNA do not initiate RNA interference in the same way as double - stranded RNA.

Answer:

B. double - stranded RNA
