What is the region within a dividing cell where chromatids and homologous chromosomes align in both mitosis and meiosis

In metaphase I, the homologous chromosomes line up at the metaphase plate. In anaphase I, the homologous chromosomes are pulled apart and move to opposite poles. Sister chromatids are not separated until meiosis II.

occur in the cell nucleus

Explanation:

Mitosis and meiosis are part of the cellular reproduction processes that occur in living beings. They create cells that will serve the most diverse biological goals. In mitosis, the cells are identical to its mother cell. In meiosis, four daughter cells are created with half of the genetic material coming from the mother cell.

During the two processes, within the nucleus of the dividing cell, the chromatids and homologous chromosomes are aligned.
