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
And what you might have noted is although we described how to make predictions about these properties, I didn't talk too much about what it actually means, what the ramifications of these different properties are.
而大家可能已经注意到了我们描述了,如何对这些性质进行预言,但是我并没有讲这到底有什么意义,这些不同性质的分支是什么。
You could distinguish between some properties of these processes that extend out, in that most of them are what are called dendrites.
你可以分辨出细胞体,所向外伸展的突起之间的,某些不同性质,大部分突起都属于树突
So it's which of these partials are sounding within each of these instruments, and the physical properties of each of these instruments are different.
所以是因为每种乐器发出的泛音不同,每种乐器的物理性质,都是不同的
in nature and composition? -Yes.
是在结构性质上不同吗?,-对。
Now this behaves very differently in water because part of it is water soluble, this part is, it's a molecule that would like to dissolve in water and part of it is like oil, it doesn't want to dissolve in water.
它们在水中表现出十分不同性质,因为一部分是水溶性的,这一部分是,是一种可以溶于水的分子,而另一部分就像油,不会溶于水中
Synthesis always occurs in one direction and that makes sense to you now because you know there's a directionality and the chemistry is different going one way than the other and this DNA polymerase only works on the chemistry going in one direction.
NA复制过程是单向的,现在你们该明白原因了,因为DNA单链有方向性,DNA在两个方向上化学性质不同,DNA聚合酶,只在一个方向上起作用
