Solution

The various changes that occur in the nucleus of the cell during: (a) prophase of mitotic division are -

Centrioles start moving apart and reach opposite poles.

Chromosomes become distinct.

Chromosomes are already duplicated as paired chromatids.

Sister chromatids attach to each other at a small region called centromere.

Spindle fibres appear between daughter centrioles.

Nuclear membrane and nucleolus disappear.
