Identify the true statements about RNA interference. Select all of the true statements. miRNAs are short duplexes approximately 21 nucleotides long. miRNAs suppress gene expression by interfering with transcription. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNA is cleaved by the Dicer enzyme complex. Small RNAs interfere with gene expression by interacting with mRNA, bringing about mRNA degradation.
