Question:

Kinetochores are associated with

Options:

1. Outer part of primary constriction
2. Centromere in its inner central part
3. Secondary construction
4. Satellite

Solution:

Kinetochores are associated with the centromere in its inner central part. The centromere is a specialized region on the chromosome that helps to attach the chromosome to the spindle fibers during cell division. The kinetochore is a protein complex that forms at the centromere and interacts with the spindle fibers, helping to pull the chromosomes apart during mitosis or meiosis. Therefore, option 2 is correct. The primary constriction is a narrow region on the chromosome where the spindle fibers attach during cell division. The secondary constriction is a region on some chromosomes that appears constricted but does not play a role in attachment to the spindle fibers. The satellite is a small, condensed region of DNA that is attached to the rest of the chromosome by a thin strand of DNA.
