The viral DNA is injected through the tail into the host cell, where it directs the production of progeny phages.

该病毒DNA通过尾巴注入宿主细胞，在这里指导后代噬菌体的产生。

Another drug might incapacitate the mechanisms the bacteria use to divert lipids from the host cell to the chlamydial vacuole, halting the trespassers' ability to hide.

另一种药物，则是造成披衣菌挪用宿主细胞脂质的机制失效，使得这些非法入侵者无法藏匿。

Like other viruses, HIV needs a host cell to multiply.

像其它的病毒一样，HIV病毒也需要一个主体细胞来繁殖。

Take a plasmid, cut it open, insert a gene that we want into the plasmid, and then put that plasmid in a host cell, and let the host replicate it.

取一个质粒,把它切开,把目标基因放进去,然后把这个质粒植入到宿主细胞,让宿主来进行复制

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

That DNA gets replicated to make many more copies of the viral DNA using host mechanisms, that is, often using the DNA polymerase which is naturally present in the host cell for its own replication.

病毒DNA进行复制,通常是利用在宿主细胞自身的有关物质,利用宿主细胞中天然存在的,DNA聚合酶来大量复制病毒DNA

DNA, which the host cell then unwittingly uses to make more viruses.

And, as a bonus, it is the protein that locks on to the surface of a host cell before the virus enters it.
