host cell

基本解释

For many scientists, viruses do not qualify as alive due to their inability to reproduce without the help of a host cell.
很多科学家认为，病毒不符合生物的定义，因为他们无法脱离宿主细胞自行繁殖。
Martin has shown that, of the eukaryotic genes whose ancestry can be traced, 75 per cent or more came from bacteria rather than the host cell.
马丁揭示，在哪些可以追溯到祖先的线粒体基因上，有75%或更多的成分来自当时外来的细菌而非宿主细胞。
Scientists speculated that every now and then a retrovirus inserted itself into a host cell and then failed to turn it into a virus factory.
科学家推测逆转录病毒将自身插入到宿主细胞，常常并不能把它变成一个病毒工厂。

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
