host cell

基本解釋

For many scientists, viruses do not qualify as alive due to their inability to reproduce without the help of a host cell.
很多科學(xué)家認(rèn)為，病毒不符合生物的定義，因為他們無法脫離宿主細(xì)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.
馬丁揭示，在哪些可以追溯到祖先的線粒體基因上，有75%或更多的成分來自當(dāng)時外來的細(xì)菌而非宿主細(xì)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.
科學(xué)家推測逆轉(zhuǎn)錄病毒將自身插入到宿主細(xì)胞，常常并不能把它變成一個病毒工廠。

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.
取一個質(zhì)粒,把它切開,把目標(biāo)基因放進(jìn)去,然后把這個質(zhì)粒植入到宿主細(xì)胞,讓宿主來進(jìn)行復(fù)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.
所以當(dāng)接收到正確的信號,恰當(dāng)?shù)腡細(xì)胞尋覓到,感染外源病毒的細(xì)胞時,首先發(fā)生的是,T細(xì)胞被激活并開始增殖,制造更多自身拷貝

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進(jìn)行復(fù)制,通常是利用在宿主細(xì)胞自身的有關(guān)物質(zhì),利用宿主細(xì)胞中天然存在的,DNA聚合酶來大量復(fù)制病毒DNA

It is capable of recognising the signature of cervical cancer and destroying the host cell when it is found.
