Question

During metaphase I, the spindle fibers attach to the _______ on the chromosomes.

• A. kinetochore
• B. centrosome
• C. centromere
• D. centrioles

Answer 1

The correct option is A kinetochore

During metaphase I of meiosis I, the spindle fibres attach to the kinetochores of the homologous chromosomes. The kinetochore is a proteinaceous disc-shaped structure near the centromere.


The centriole and centrosome are structures responsible for the organization of the spindle fibres.
The centromere is the structure which holds the sister chromatids of the chromosomes together.
