During karyokinesis, the spindle fibres ...

During karyokinesis, the spindle fibres get attached to condensing chromosome at a highly differentiated region. This region is called as

A

chromomere

B

chromocentre

C

centriole

D

kinetochore.

Text Solution

Verified by Experts

The correct Answer is:
D
The key feature of metaphase is the attachment of spindle fibres to kinetochores of chromosomes. Kinetochores are disc-shaped structures at the surface of the centromeres. These strutures serve as the sites of attachement of spindle fibres to the chromosomes that are moved toward poles.
