Which statement accurately describes the relationship between RNAi, small interfering RNA (siRNA), and miRNA?
A) They all describe different methods of post-translational gene regulation.
B) miRNAs are classified into two types: RNAi molecules and siRNAs.
C) RNAi occurs in two ways: by miRNAs or by siRNAs.
D) RNAi is accomplished by siRNA and miRNA, but only siRNAs are cleaved by Dicer proteins.
E) miRNAs are transcribed from viruses, while siRNAs are transcribed from nuclear DNA; both are types of RNAi.

Question

Quizplus · Accepted Answer

RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules. This process can occur in two main ways: through microRNAs (miRNAs) or small interfering RNAs (siRNAs). Both miRNAs and siRNAs play crucial roles in gene silencing, but they originate from different types of RNA precursors and have slightly different mechanisms of action.
