Explanation:
Detailed explanation-1: -Cohesin forms rings that hold the sister chromatids together, whereas condensin forms rings that coil the chromosomes into highly compact forms. The mitotic spindle also begins to develop during prophase .
Detailed explanation-2: -Sister chromatids are physically held together by cohesin, which is a protein complex consisting of four core subunits (Fig.
