RNA molecules form double stranded helices, just as do DNA molecules, by Watson Crick pairing of nucleotides on the two complementary strands of the helix. RNA分子能像DNA分子那样形成双链螺旋，通过沃森·克里克配对，两个螺旋的核苷链互补。 - 2
Mammalian cells make only the single-stranded variety. If a cell’s defence mechanisms detect double-stranded RNA they destroy it, to protect against infection. 哺乳动物细胞只能识别单链RNA,如果细胞的防御机制发现了双链RNA就会破坏它以保护机体不受病毒的感染。 - 3
This aversity to double-stranded RNA means short hairpins can be used to knock out the messengers, thus nullifying the signal from the underlying gene. 哺乳动物细胞对双链RNA不识别意味着可用短发卡RNA来阻断信使RNA,从而使相应基因的信号无法传递。
