You load them into the top of a gel and a gel is - in this case it's synthetic polymer gel but it looks very much like Jell-O.

你把它安置在一段凝胶上,凝胶是--,这种合成凝胶聚合物看上去很像吉露果冻

We'll talk about exactly what a gel is later when we talk about biomechanics and cells are suspended within it.

之后当我们谈到生物力学的时候,会具体讲讲这个凝胶是什么,以及细胞是怎样悬浮在其中的

This collagen is highly hydrated, it forms a gel that has water-like properties but it also has solid properties.

这些胶原蛋白是高度水合的,形成了既有水的特性,又具有固体特性的胶体

That matrix has properties that vary in different locations in the body, but basically it's a highly hydrated or water-rich gel.

这种基质的性质,随其所在身体部位的不同而不同,但基本是高度水合的,即富含水的凝胶

They're going to move from a negative pole to a positive pole, so they're going to move through this gel.

它们会从负极移向正极,会通过这块凝胶板

Because it's a gel electricity is going to move through the gel because there are ions in it the same way - for the same reason you don't drop an electrical device into the bathtub because charge moves through water that has ions in it.

由于凝胶中存在离子,电流会通过凝胶,同样--,因为同样的原因你不会把电器扔进浴缸里,因为水里也有离子,所以水可以导电

If this was a sickle patient, so they had this gene instead it wouldn't get cut and when I went to look for that presence of that gene on this gel, it would appear as one large segment instead of a large one and a smaller one.

而如果是个镰状红细胞贫血的病人,他们的基因是不会被限制酶切割的,因此他们基因的凝胶电泳结果就不会呈现,一大一小的结果,而只有一个大的片段

We're going to take a chromosomal DNA, we're going to digest it with this restriction enzyme, we're going to put it in this tube and run it on a gel, and we're going to see what results down here.

我们取一条染色体DNA,然后用限制酶进行分解,接着再放,在凝胶上进行电泳,之后看看结果如何
