Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which term describes centromeres uncoupling, sister chromatids separating, and the two new chromosomes moving to opposite poles of the cell?
A
telophase
B
anaphase
C
metaphase
D
prophase
Explanation: 

Detailed explanation-1: -Anaphase. The sister chromatids separate from one another and are pulled towards opposite poles of the cell. The microtubules that are not attached to chromosomes push the two poles of the spindle apart, while the kinetochore microtubules pull the chromosomes towards the poles.

Detailed explanation-2: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes.

Detailed explanation-3: -Which term describes centromeres uncoupling, sister chromatids separating, and the two. new chromosomes moving to opposite poles of the cell? anaphase.

Detailed explanation-4: -Anaphase stage is characterized by the following key events: Centromeres split and chromatids separate. Chromatids move to opposite poles.

Detailed explanation-5: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
