During metaphase, spindle fibers attach to chromosomes at the what?

Explanation:
Spindle fibers attach to kinetochores that sit at the centromere of each chromosome. This connection pulls sister chromatids toward opposite poles and helps align them along the cell’s equatorial plane during metaphase. A chromatid is one copy of a duplicated chromosome, a chromosome is the entire DNA-protein structure, and the nucleolus is the ribosome-producing region that disassembles during mitosis. So the attachment site is the centromere (via kinetochores).
