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，着丝粒纵裂，姐妹染色单分离。

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由着丝粒连接的相同染色单。

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

纺锤丝缩短了，着丝粒分裂，所以每个染色变成两个独立的染色单。

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，附着在着丝粒的染色上。

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

中期 2，着丝粒与纺锤丝连结。

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

如果两条染色粘合在起，你会期望找到两个中心，或着丝粒。
