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。

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。

The HIV retrovirus, in particular, is a single-stranded RNA virus that duplicates itself in a host cell by converting its genetic code into double-stranded DNA that is then inserted into the host cell.
