Spindle fibres attach on to the _ chromosome?
Correct answer: D. Kinetochore of the chromosome
- A. Centromere of the chromosome
- B. Kinetosome of the chromosome
- C. Telomere of the chromosome
- D. Kinetochore of the chromosome
Explanation
Small disc-shaped structures at the surface of the centromeres are called kinetochores. These structures serve as the sites of attachment of spindle fibres to the chromosomes that are moved into position at the centre of the cell.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
