Question

Kinetochore is present on _______.

• A. Granule within centromere
• B. Surface of centromere
• C. Constriction near chromosome end
• D. End of chromosome

Answer 1

The correct option is A Granule within centromere

• The centromere is the lighter staining region on the chromosome of a cell which appears as a constriction.
• They are also known as primary constriction or kinetochore.
• The kinetochore is a proteinaceous structure that assembles at the surface of the centromere which forms the site for binding of spindle fibres during cell division.

So, the correct answer is 'Surface of centromere'.
