Answer:
The separation of sister chromatids occur during anaphase.
Explanation:
Sister chromatid is the single half copy of a chromosome. Two sister chromatids are joined together by the centromere.
Anaphase stage of cell division ( mitosis and meiosis) leads to the separation of sister chromatids. Two important enzymes involved in the process of sister chromatid separation are securin ans separase.
Thus, the answer is anaphase.
