1. The nucleus is located prior to mitosis
2. New spindle microtubules form at either end
3. Chromatids remain attached to one another until anaphase
4. Chromosomes are grouped during telophase

Respuesta :

Answer:

Option 3, Chromatids remain attached to one another until anaphase

Explanation:

Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.

Hence, option 3 is correct
