Which of the Following Molecules Participates in RNA Interference

Question

Which of the following molecules participates in RNA interference?
A) siRNA
B) tRNA
C) rRNA
D) dsDNA
E) All of these are correct.

Accepted Answer

RNA interference involves the use of short interfering RNAs (siRNAs) that are typically 20-25 nucleotides in length and function to degrade or inhibit the expression of specific target messenger RNAs (mRNAs). tRNA and rRNA are involved in translation, while dsDNA is not an RNA molecule and does not participate directly in RNA interference.
