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

紧随其后的是后期 2，在这一阶段，粒纵裂，姐妹染色离。

The DNA is exactly replicated, and each chromosome now becomes two identical chromatids joined by the centromere.

DNA 被精确地复了，每条染色现在变成了两条粒连接的相同染色。

The spindle fibers shorten and the centromere divides, so each chromosome becomes two separate chromatids.

纺锤缩短了，粒裂，所以每个染色变成两个独立的染色。

The microtubules invade the nuclear region after the nuclear envelope disintegrates, attaching to the chromosomes at the kinetochore.

核膜解后，微管侵入核区，附在粒的染色上。

In metaphase 2, the centromeres contain two kinetochores that attach to spindle fibers from the centrosomes at opposite poles.

中期 2，粒与纺锤连结。

If two chromosomes were glued together, you'd expect to find two centers, or centromeres.

如果两条染色粘合在一起，你会期望找到两个中心，或粒。
