Using cellulose (CF-11 ) chromatography a double stranded RNA was purified from the extract of R. sativus-root, termed E.
本实验用CF-11纤维素柱层析，从白萝卜提取物中分离纯化到一种双链RNA，简称E。
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。
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。
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。
In 1998, scientists identified RNAi, a mechanism that primitive organisms use to detect and destroy virus's double-stranded RNA and any viral mRNA.
1998年，科学家发现了RNAi，这是一种原始生物用来检测和摧毁病毒的双链rna和任何携带病毒的mRNA的机制。
When sense and antisense RNA molecules meet, they bind to each other and form double-stranded RNA.
当感觉和抗感觉RNA分子相遇的时候，他们结合在一起形成双链的RNA。
In every experiment, injection of double-stranded RNA carrying a genetic code led to silencing of the gene containing that particular code.
在每一次实验中，注射携带了一种遗传密码的双链rna都导致了包含这种密码的基因的关闭。
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。
Could it be that such a double-stranded RNA molecule silences the gene carrying the same code as this particular RNA?
会不会是这个双链rna分子关闭了携带相关遗传密码的基因？
This paper reports a new method based on double-stranded RNA (ds RNA) analysis for detection of apple latent viruses.
