That makes sense and it seems like getting rid of some of this division of regulatory agencies is very beneficial.
这样就变得更合理,也有利于解决两个不同的,监管机构的领域相相争问题。
-
Well, what if this division takes place in an environment where there's one kind of extra cellular matrix here and another kind of extracellular matrix here?
那如果在细胞分裂的过程中,两个子细胞的细胞外基质不同,会对它们产生什么影响
-
At that stage we can merge these, and then take this down, do the division merge and bring them back up.
在那里做一次分解，做到这步时，我们可以把这些进行合并，然后把这个拿下来,做分解合并过程后再把它们拿回去。
-
It's really the multiplication and in this case, division that the problem arises. Yeah?
这里实际上是乘法和，除法引起了那个问题，请说？
-
The popular, old-fashioned Frost and the elite, modern Frost--these roles point to a division in the audiences for poetry that emerges clearly in this period.
这个大受欢迎，旧式的弗罗斯特和那个高雅的，现代的弗罗斯特，这些角色指出了观众的分化,因为诗歌在这个阶段表现的是那个。
-
So there's a loss of potential in this division.
因此,在分化中祖细胞损失了些潜能
-
This stem cell which is reproduced still has the potential to undergo asymmetric division but this one does not.
新生成的干细胞,仍然有潜能进行不对称分裂,但定向祖细胞就不行
-
This process of cell proliferation or cell division is, of course, very important during development of an embryo.
细胞增殖和分裂的过程,在胚胎发育中至关重要
-
In fact, there are differences that can be detected upon the first cell division where this zygote divides through the process of mitosis.
事实上,受精卵在进行,第一次有丝分裂时,就会产生差异
-
So this stem cell division leads to another stem cell as well as a committed progenitor cell.
这种细胞分化不仅产生一个定向祖细胞,还会产生另一个干细胞
-
So hopefully there is indeed a way to fix this, but it looks as though the division operator, the single slash is division but -- and here's a curiosity about many programming languages -- because 17 is an integer and because 13 is an integer, why do I say that?
我的确希望有一个方法来修正这个错误，但是看起来,好像那个除法操作，那个斜杠是除法,但是--对于很多编程语言来说,是挺奇怪的--因为17是一个整数,13也是一个整数，为什么我这样说？
-
We talked about last time that part of the process of going from this single cell to multi cellular many celled organisms like we are is cell division.
我们上节课说过,从一个单细胞分裂形成大量细胞,构成的器官的过程,叫做细胞分裂
-
There's one division, here it shows it at the 16 cell stage and then here, and this transformation as it goes from 16 cells to more like 64 cells.
这是第一次分裂,这里显示的是十六细胞期,然后在这里,在这里胚胎进一步的产生了变化,由十六个细胞分裂为约六十四个
-
One result of this asymmetrical division is a committed progenitor cell.
这种不对称分裂的一个结果,是产生定向的祖细胞
-
It goes - going through this process of amplifying divisions, every division increasing the number of cells by a factor of two and these cells becoming more differentiated around the way.
它经历了一系列扩增性的分裂过程,每次分化,细胞数目都翻一番,而在此过程中细胞分化得更成熟
-
There are cells within your body that are always in the process of division and forming new cells, and sometimes this is for a tissue where cells only have a finite lifetime.
你体内的一些细胞,始终在不断分裂,并生成新的细胞,很多时候,是在一些细胞寿命有限的组织中
-
This is an example of that asymmetric division.
这就是一个典型不对称分裂的例子
-
In the time it takes for one cell division to occur, it could be that this cell entraps a different chemical composition of the cytoplasm then this entraps, and that's a well known concept.
当一个细胞分裂发生期间,很可能这个细胞截留了一种不同的,细胞质化学组分,这种非对称分裂是一个广为人知的概念
-
Potential refers to what it sounds like, 'what potential does this committed progenitor cell have?' 'What potential does this stem cell have?' Well, one way to think about is that upon this first division, this asymmetric division, this committed progenitor cell has lost some potential.
这个"潜能"和字面意思相同,定向祖细胞的潜能是什么,干细胞的潜能又是什么,一种看法就是在第一次分化时,即不对称分裂时,定向祖细胞失去了一些潜能
-
There could be differences in the physics of cell division, this process of separating into two cells such that even though they both have the same chromosomes, they both have the same DNA content, maybe one of the cells entraps something that's different than the other cells.
细胞分裂的过程中的确可能会产生差异,在分裂为两个细胞的过程中,尽管两个子细胞含有相同的染色体,含有相同的DNA组成,但也许其中一个细胞,截留了和其他细胞不同的物质
