Detailed explanation-2: -The centromere is the point at which two chromatids of a chromosome are held together.
Detailed explanation-3: -Sister Chromatids Are Joined Together at Centromeres In addition to their kinetochore-related function, centromeres perform another essential role in mitosis by serving as the sites of sister chromatid cohesion. For accurate mitoses, sister chromatids must remain attached until the spindle checkpoint has been passed.
