Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what stage are chromosomes separated and moved to opposite poles?
A
prophase
B
metaphase
C
anaphase
D
telophase
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: -In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

Detailed explanation-3: -During anaphase II, microtubules from each spindle attach to each sister chromatid at the kinetochore. The sister chromatids then separate, and the microtubules pull them to opposite poles of the cell.

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.
