chromatid - mitosis

Postby curious1234 on Mon Feb 04, 2008 2:08 am

I'm confused. During mitosis are spindles attached to centromeres or kinetochore of a chromatid? Some information I read says on, some says the other and then I've also read that spindles attach to both. Is this possible?

the centromere is a region of the chromosome. The kinetochore is a specialized structure that attaches to the spindle. The spindle microtubules directly attach to the kinetochore.

As what MrMistery said, the spindle fibers actually attach to the kinetochore which are located within the centromere.

The centromere is composed of kinetochore fibers which attach to the spindle fibers.

centromeres are starting point of spindles. They stabilize these spindles, like anchors...

kinetochore is the specialized proteinaceous part of the centromere to which the spindle fibres attach.
