Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
At which phase are the sister chromatids separated and are moved to opposite sides of the cell?
A
Interphase G2
B
Prophase
C
Prometaphase
D
Metaphase
E
Anaphase
Explanation: 

Detailed explanation-1: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.

Detailed explanation-2: -A central feature of mitosis is segregation of sister chromatids to opposite poles during anaphase.

Detailed explanation-3: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.

Detailed explanation-4: -Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules.
