Question

Which structure is present in chromosomes?

• A. Nucleus
• B. Centrosome
• C. Golgi body
• D. Centromere

Answer 1

Answer: (D)

Centromere provides structure to the cell. The sister chromatids are linked together at the centromere. During mitosis, spindle fibers attach to the centromere via kinetochore. Their physical role is to act as the site of assembly of the kinetochore, a highly complex multiprotein structure that is responsible for the actual events of chromosome segregation, i.e., binding microtubules and send signals to the cell cycle machinery.

So, the correct answer is option C.
