Microtubules that attach to the kinetochores are known as kinetochore microtubules.

附着在动粒上的微管称为动粒微管。

Non kinetochore microtubules lengthen, pushing the centrosomes farther apart.

非动粒微管变长，将中心体推向更远的距离。

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。

The kinetochore functions as a motor, pulling the chromosome along the attached microtubule.

动粒起着马达的作用，沿着附着的微管拉着染色体。

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

核膜解体后，微管侵入核区，附着在着丝粒的染色体上。
