Question

which structure is responsible for pulling sister chromatids apart during mitosis? a mitotic spindle b centromere c cell plate d nuclear membrane

Explanation:

The mitotic spindle, made of microtubules, attaches to the kinetochores of sister - chromatids and pulls them apart during anaphase of mitosis. The centromere is the region where sister - chromatids are joined. The cell plate forms during cytokinesis in plant cells to separate the two daughter cells. The nuclear membrane breaks down during prophase and reforms during telophase.

Answer:

A. Mitotic spindle
