During this process, the viruses create long strings of double-stranded RNA (dsRNA), which is not found in human or other animal cells.

在这一过程中，病毒创建长链的双链rna，这一结构在人体和其他动物体细胞中没有发现。

Objective Recently, a naturally occurring gene silencing mechanism triggered by double-stranded RNA (dsRNA), RNA interference (RNAi), has been described in a number of species including Drosophila.

目的近年来，双链rna介导的基因沉默(RNA干扰)已在许多动植物中发现，并成为研究基因功能的强有力的工具。
