The chiasmata remain on the chromosomes until they are at the transition to anaphase 1.

交叉保留在染色体上，直到它们过渡到后期 1。

The four main steps of meiosis 2 are: prophase 2, metaphase 2, anaphase 2, and telophase 2.

裂 2 的四个主要步骤是：前期 2、中期 2、后期 2 和末期 2。

Anaphase 1 Kinetochore microtubules shorten, pulling homologous chromosomes, which consist of a pair of sister chromatids, to opposite poles.

后期 1动粒微管短，将由一对姐妹染色单体组成的同源染色体拉向相反的两极。

This is followed by anaphase 2, in which the remaining centromeric cohesion is cleaved, allowing the sister chromatids to segregate.

随其后的是后期 2，在这一阶段，着丝粒纵裂，姐妹染色单体离。

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。

I think I kind of know what's going on 'cause I remember mitosis and anaphase a little bit from college and high school, but that's just way too complicated.

我想我差不多知道发生了什么，因为我记得大学和高中的时候有一点有丝裂和后期，但这太复杂了。

And in anaphase, these condensed pieces of DNA in the cell are pulled apart into separate sides of the cell in preparation for the cell becoming not one cell but two cells.

在后期，细胞中这些浓缩的 DNA 片段被拉到细胞的不同侧面，为细胞成两个细胞而不是一个细胞做准备。

So if I was even to double simplify that explanation, I would go even further and say, anaphase is when the condensed genetic material or chromosomes are pulled apart to the separate sides of the cell.

因此，如果我要把这个解释简化一倍，我会更进一步说，后期是浓缩的遗传物质或染色体被拉到细胞的不同侧面。
