Every cell in your body is only using a fraction of the DNA that's available to it.

每个细胞只用到了,决定该细胞生物功能的DNA片段

Because HIV is an RNA virus and if it enters your cell the only way it can replicate, it can put its DNA into your cells, is by first making DNA out of its RNA genome.

因为HIV是RNA病毒,如果它进入你的细胞,它复制自己的唯一方式,它能把自己的DNA转入你的细胞,方法是先用自己的,RNA基因组制造出DNA

So, when the right signal is received, the right T-cell finds your host cell with a foreign virus in it, the first thing that happens is that this T-cell becomes activated and it starts reproducing, making more copies of itself.

所以 当接收到正确的信号,恰当的T细胞寻觅到,感染外源病毒的细胞时,首先发生的是,T细胞被激活并开始增殖,制造更多自身拷贝

And you could interfere with a translation by degrading messenger RNA, for example. If you had a way to specifically chew up all the RNA molecules that are responsible for making a particular protein, you could stop it from being expressed even though your cell is trying to make it.

而你就可以通过,降解其mRNA来进行干扰,再举个例子,如果你能把表达特定蛋白的RNA,统统揪出来捣毁的话,你也能阻止这段基因表达,哪怕是你的细胞在努力表达这段基因
