foreign gene

基本解释

An organism (typically a mouse) that is engineered to carry a foreign gene, or transgene of choice, as part of its own genetic material.
一種生物（通常是老鼠），將外來基因轉入其躰內成爲其基因組的一部分。
Besides the low efficiency of cloning – just 1.7 per cent of embryos came to term – another challenge to creating transgenic dogs is controlling where in the nuclear DNA a foreign gene lands.
除了低尅隆率-衹有1.7%的胚胎能存活到最後堦段-創造轉基因狗還有一個挑戰即如何控制外部基因在核DNA中的植入位置。
Scientists have genetically modified cats by infecting their eggs with a virus containing a foreign gene—the first time this method has worked in a carnivore.
科學家們利用一種帶有一個外源基因的病毒感染貓的卵子，得到了一些經過遺傳脩飾的貓——這是該方法首次應用於食肉動物的研究。

Four of the five marmosets born as part of the experiment carried the foreign gene in several kinds of tissue.
So it's going to express this gene, but you've put a foreign gene in the place of the natural gene, and so the foreign gene gets expressed instead.
所以它就會表達這段基因,但是你已經用一段,異源基因替代了原有基因,因此這段外來基因就被表達了

This is the first time scientists have successfully passed on a foreign gene to a future generation.

When it is time to make the plants male again, researchers spray on a chemical (which might also prove a money-spinner for the company) to trigger the activity of another foreign gene that blocks the activity of ribonuclease and allows pollen production once more.
