When cells divide by mitosis, the number of cells increases, and hence the organism grows.

当通过有分裂分裂，数量增加，因此生物体生长。

Mechanically, the process is similar to mitosis, though its genetic results are fundamentally different.

从机制上讲，这个过程与有分裂相似，尽管它的遗传结果是根本不同的。

As cells grow and divide, they naturally create clones by dividing in a process called mitosis.

随着的生长和分裂，它们通过有分裂的过程自然地创造克隆。

In this video, we are going to learn all about mitosis, the process of cell cloning.

在这个视频中，我们将学习有分裂，克隆的过程。

This can also happen at some point during mitosis, and the result is another mosaic karyotype.

这种情况也可能发生在有分裂过程中的某个刻，结果是形成另一个马赛克核型。

Similar to mitosis, cells also pass through the Interphase, G1, S and G2 phase before they enter Meiosis.

与有分裂相似，在进入减数分裂之前也经历了间期、G1、S 和 G2 期。

Not Sheldon. Over the years, we've formulated many theories about how he might reproduce. I'm an advocate of mitosis.

除了谢尔顿。多年来我们通过各种理探究他将如何繁衍后代。我主张的是有分裂。

Simply put, mitosis is a way cells divide.

简而言之，有分裂是分裂的一种方式。

And so all mitosis is is one cell forming two cells.

有分裂就是一分裂成两。

This might mean spending a full two hours understanding mitosis or something like that, but it's so, so important.

这可能意味着要花整整两个小来了解有分裂或类似的东西，但这非常重要。

So you just read a dense page of a textbook on mitosis.

所以你只是读了一本关于有分裂的教科书的密集页面。

So when you're replacing cells in your body you're doing it through mitosis.

因此，当你在体内替换，是通过有分裂来完成的。

So mitosis is how we replace cells in the body.

所以有分裂是我们如何在体内替换的。

From this video, you should now know that mitosis is how cells divide in order to grow and repair, or for asexual reproduction.

通过这个视频，你现在应该知道有分裂是为了生长和修复或无性生殖而分裂的过程。

When the membranes of the two pronuclei rupture, chromosomes go flying, and boom, you officially have a diploid zygote, which almost immediately starts mitosis.

当两个原核的膜破裂，染色体飞舞，嘣，你正式有了一个二倍体合子，它几乎立即开始有分裂。

Now we're not going to go into the specifics of mitosis and meiosis.

我们不会深入探讨有分裂和减数分裂的具体节。

Part one is going to be the division of the nucleus, and we call that in general mitosis.

第一部分是核的分裂过程，我们通常称之为有分裂。

And so that one fertilized egg, that one zygote is going to copy itself through mitosis and make a bunch of cells.

那么那个受精卵，那个受精卵将会通过有分裂复制自己并产生许多。

And you practiced the explanation three times until you had an amazing simplified explanation of all the phases of mitosis.

你练习了三次解释，直到你对有分裂的所有阶段都有了一个惊人的简化解释。

Cells that are broken, cells that are broken down, cells that we need to replace, we do that through mitosis.

通过有分裂，我们修复受损、分解废弃以及替换所需更新的。
