Correct answer: B. Kinetochore
- A. Telomere
- B. Kinetochore
- C. Primary constriction
- D. Secondary constriction
Explanation
A disc-shaped protein structure within the centromere to which the spindle fibers attached during mitosis or meiosis called the kinetochore. Kinetochores are large protein assemblies that connect chromosomes to microtubules of the mitotic and meiotic spindles in order to distribute the replicated genome from a mother cell to its daughters. The kinetochore is a protein structure that assembles at the centromere's surface, forming the site for binding spindle fibers during cell division.

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.
