During cell division, the spindle fibres attach to the chromosome at a region called

1. chromocentre
2. kinetochore
3. centiole
4. chromomere

Correct answer: kinetochore

Solution

Spindle fibres bind to the kinetochore, a specialized protein structure assembled on the centromere of each chromosome. This connection allows chromosomes to be moved apart accurately during cell division.
