An example of a small interfering ribonucleic acid (siRNA) molecule is shown at the top in orange and red. Once inside the cell, the siRNA molecule is picked up by an Argonaute protein, shown at the bottom in blue. The Argonaute protein strips away one strand from the siRNA and then looks for any messenger RNA within the cell that matches it. If it finds one, it cleaves the RNA, destroying it.
