Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides.
<span><span>
G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>
S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>
G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>
M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>
The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.
<span>Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.</span>

Answer:
answer; if u adjust the diagram on the chart it should be a little bit narrow and small but exact the diagram consist different altitudes and scopes. use
Explanation:
why well because think about it your question is what happens when the diagram on the microscope adjusts to easily.
Sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
<h3>What is Meiosis?</h3>
Meiosis is a particular type of cell division by which gametes (germinal cells are generated) through two division cycles known as Meiosis I and Meiosis II.
During Meiosis I homologous chromosomes are separated, thereby ensuring the correct segregation of sister chromatids during Meiosis II.
In conclusion, sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
