Scientists thought that most RNA in a cell was messenger RNA generated by protein-coding genes, RNA in ribosomes, or a sprinkling of other RNA elsewhere.
A completely different approach is to use RNA interference, a relatively new technique for switching off individual genes by delivering short stretches of RNA.
另一种完全不同的方法是RNA干扰。它采用相对较新技术通过转录小rna分子来关闭各别基因。

Instead, the naked viral RNA may alter the function of the cells through a mechanism similar to RNA interference, in which the presence of certain RNA sequences can turn genes on and off.
