The place of centromere where spindle fibres get attached is_________?
Correct answer: A. Kinetochore
- A. Kinetochore
- B. Kinochore
- C. Centromere region
- D. all of these
Explanation
The kinetochore is a protein-containing structure assembled at the centromere, and spindle-fibre microtubules attach to it during cell division. Students may choose the centromere region because the kinetochore is located there, but the centromere itself is the DNA region, not the direct spindle attachment structure.
