The following questions refer to the essential steps in meiosis described below.
1. formation of four new nuclei, each with half the chromosomes present in the parental nucleus
2. alignment of tetrads at the metaphase plate 3. separation of sister chromatids
4. separation of the homologues; no uncoupling of the centromere
5. synapsis; chromosomes moving to the middle of the cell in pairs
which of the steps take place in both mitosis and meiosis?

3. Separation of sister chromatids

Explanation:

Before entering mitosis or meiosis, DNA contained in a cell duplicates and  and each chromosome will have two sister chromatids.

In mitosis the sister chromatids separate to produce two daughter cells that have the same information as the original cell before the DNA duplicated.On the other hand, meiosis consists of two cell divisions. During meiosis I, homologous chromosomes separate, producing two daughter cells that have half the information the original cell had, but each chromosome still has two sister chromatids. During meiosis II, the sister chromatids separate, and each daughter cell produces two more daughter cells, that now have a single homologous chromosome of the pair, and which has a single chromatid.
