At metaphase, chromosomes are attached to the spindle fibres by their:

Correct answer: C. Kinetochores

  • A. Satellites
  • B. Secondary constrictions
  • C. Kinetochores
  • D. Centromeres

Explanation

The key feature of metaphase is the attachment of spindle fibres to kinetochores of chromosomes. Kinetochores are disc­shaped structures at the surface of the centromeres. These structures serve as the sites of attachment of spindle fibres to the chromosomes that are moved into position.

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.
