Question
Assertion: Kinetochore is essential for cell division. Reason: Kinetochore serves as the sites of attachment of spindle fibres to the chromosome.
Step 1
The kinetochore is a protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart. It is essential for cell division as it serves as the site of attachment for spindle fibers to the chromosomes. Show more…
