Spindle fibres unite with which structure of chromosomes :Kinetochores are disc-shaped protein structures at the centromere of each chromatid.
The spindle fibres (kinetochore microtubules) attach to the kinetochores and pull the chromatids to opposite poles during anaphase.
The centriole is not part of the chromosome; it organises the spindle.
So spindle fibres unite with the kinetochore.
