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

随着细胞的长和分裂，它们通过有丝分裂的过程自然地创造。

Mitosis produces identical copies of cells and is how most of our cells divide.

有丝分裂产相同的细胞，这是我们大多数细胞分裂的方式。

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

这种情况也可能发在有丝分裂过程中的某个刻，结果是形成另一个马赛核型。

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

除谢尔顿。多年我们通过各种理论试图探究他将如何繁衍后代。我主张的是有丝分裂。

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

所以你只是读一本关于有丝分裂的教科书的密集页面。

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解有丝分裂或类似的东西，但这非常重要。

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

你练习三次解释，直到你对有丝分裂的所有阶段都有一个惊人的简化解释。

So if we were gonna talk about a specific phase of mitosis, for example, anaphase, a two complicated explanation might be something like this.

因此，如果我们要谈论有丝分裂的一个特定阶段，例如，后期，两个复杂的解释可能是这样的。

Working as lab partners, we had to separate the slides of onion root tip cells into the phases of mitosis they represented and label them accordingly.

作为实验伙伴，我们得把洋葱根尖细胞的玻璃片按照它们所代表的有丝分裂阶段分开，并把相应的阶段标出。

Because once you have the basic framework of what mitosis is, then you can start to fill in the little small things that go into understanding mitosis more deeply.

因为一旦你有有丝分裂的基本框架，那么你就可以开始填写更深入的理解有丝分裂的小细节。

You just did so much work on mitosis over an hour of work trying to understand and learn and simplify the complex topic of mitosis.

您刚刚在有丝分裂方面做大量工作，花一个多小的工作试图理解、学习和简化有丝分裂的复杂主题。

You watched a 20 minute YouTube video on how it works and then you began to test yourself and draw out the diagrams for the steps of mitosis.

您观看一个 20 分钟的 YouTube 视频，解它是如何工作的，然后您开始测试自己并绘制有丝分裂步骤的图表。

But if you don't understand the basic concepts of mitosis at all, you won't even get up to a B, you might get a C or a D or an F.

但是，如果你根本不解有丝分裂的基本概念，你甚至不会达到 B，你可能会得到 C 或 D 或 F。
