When they make milk they have signals for turning on the betagalactoglobulin promoter and expressing the gene of interest.

泌乳的时候,β-乳球蛋白启动子受信号调控而开启,目的基因得以表达

So, this is a positive sphere of custard, and inside are little, negative bits.

这是一个带正电荷球状的乳蛋糕，里面有一些小的负电荷的小块。

When this animal makes milk, it makes all the normal milk proteins, but it also activates your gene of interest as well.

那么当这一后代泌乳的时候,它不仅表达出自身正常的奶蛋白质,也激活了目的基因的表达

You see the lactose of course from milk, and then when you get down to the cellulose, and we're talking about starches and then fiber gets involved in here too, then cereals and vegetables become the primary source of these.

你们知道乳糖来自于乳类,当你研究纤维素的时候,以及我们在这里所说的淀粉和纤维,他们最主要的来源是谷类和蔬菜

I don't know if I'd eat it if it were put in front of me, but anyways, I'm told that it looks something like this, that you have the custard with little fragments of plum inside.

我不知道,就算这东西曾经放在我面前，就算我吃过它，但是无论如何，但是有人告诉过我有些东西长得像这样，如同在一些小块的梅子,放在乳蛋糕里面。

You're taking advantage of a promoter system, or a gene activation system, that this species knows about because adult animals can make milk.

我们之所以能利用这个启动子系统,或者称之为可以被这一物种识别的,基因活化系统,是因为成年动物可以泌乳

They're used by the body for pretty immediate energy where fat is a little bit more long-term energy, and there are many types of sugars-- and these are things that you've heard-- glucose and sucrose being the most common things that you can consume in ordinary foods, and then lactose of course, from milk.

碳水化合物被身体当做是直接能源,而脂肪则更像是一种长期能量,糖的种类有很多,这些类型你们已经听说过,葡萄糖和蔗糖是最常见的形态,你们可以在一般的食物中获取,乳糖,显然来自于乳类

In this case the promoter, which is a sequence of DNA that is positioned right in front of the gene of interest, the promoter is the betagalactoglobulin promoter in this case, and betagalactoglobulin is a milk protein.

这里涉及到的启动子,也是一段DNA序列,它必须刚好位于目的基因序列前端,我们用到的是β-乳球蛋白启动子,β-乳球蛋白是乳汁中的一种蛋白
