Vedclass · Answer

(D) kinetochore is a complex protein structure that forms on the centromere of a chromosome during cell division. It serves as the attachment point for spindle fibers (microtubules) to pull the sister chromatids apart during anaphase. Since the kinetochore is located on the surface of the centromere and facilitates the attachment of spindle fibers,options $A$ and $B$ are correct. Option $C$ is also a functional description of the centromeric region where the kinetochore is situated. Therefore,all the given statements correctly describe aspects of the kinetochore.

Column $I$	Column $II$
$(a)$ $G_1$ phase	$(p)$ Synthesis of new $DNA$ occurs
$(b)$ $G_2$ phase	$(q)$ No $DNA$ synthesis occurs
$(c)$ $S$ phase	$(r)$ $DNA$ synthesis stops
$(d)$ Prophase	$(s)$ Formation of mitotic spindle occurs
